Survey, how many miles will you drive for a Dark
      #5325405 - 07/19/12 04:44 PM

That is, if a green zone is within an hour (which I think it is for 90% of Americans) how much further would you be willing to drive to get to a grey/black zone?

Hard to answer, without some additional clarification: do you mean drive that far to observe on a weekly basis, once a month, or maybe just for that special once-a-year really dark sky treat?

Once weekly: I wouldn't be willing to drive more than an hour, and am quite content to observe from my home (which is in a yellow zone).

Once monthly: maybe an hour, but definitely no more than 2

Once a year: probably 5-6 hours at most

well, I guess on an average basis, ie, no work the next day, but not some long planned trip.

about 20 miles to a pretty dark spot. Pretty close to grey

I should go there more, but I get a lot done from my backyard that is green/yellow ish

I would be willing to drive 100 miles for skies that dark, IF the weather makes such a long trip worthwhile. But generally I would much rather drive no farther than 40 or 50 miles to get to an observing site.

I just got back from a 5 hour trip to black( 7.5 NELM) skies in the White Mts. Worth every minute of the road time. The transparency and seeing were so fine the last night it really recharged my batteries. I camp so I like to spend more than one night when I make a long trip like that but I think those of us in the west are more conditioned to the greater distances. I try to stack other daytime activities to "punch a couple other tickets," too.
To give you a direct answer I'd make that 5 hour trip 3 times a year but I pick the times carefully.

My club's DSS is 54 road miles from my house. I usually go there in the fall to spring months. There is a exploratory well near it with the lights now and next month's starparty in WY where a lot of my club members go to was cancelled. We're all chomping at the bit here this summer.

Once or twice a month, weather and work permitting.

Boy, I sure doubt that a green zone is within an hour drive for 90% of Americans. Less than 50% would be my bet. I have to drive almost an hour to get to the orange zone.

People in the West have it better than people in the East, due to the proximity of vast quantities of government-owned land. But even there -- it takes more than an hour just to drive across L.A., let alone get far enough away from it to be in a green zone.

No doubt if it were an hour drive to green and a 2-hour drive to gray, I would go to green on weeknights and gray on weekends.

I drive about 70 miles to our Blue Zone spot and do it every clear weekend and some that are not.

The dark skies of the Navajo reservation are about 700 miles, we do that at least once a year.

You live in san Diego then drive to gray/black zone....you are lucky! In Illinois at least 7 hours drive to up north or drive south to pass St. Louis! Someday there might have no gray/ black zone left but I hope that I am wrong!

What Tony said - with the addition that I'd drive a little farther if the opportunity to camp/spend night were available.

Also, I drive to the west every 3 or 4 years for combined observing/hiking/camping. My last trip logged 6000 miles total.

I wouldn't do that more than every other weekend, of course.

As a relative newbie who just came back into this hobby this winter I have not yet made any long trips, mostly just observed from my Orange zone (mag 3-4 skies) in suburban CT or even a few times from white zone (mag 1 maybe...) in downtown new york city. I have not even considered trying a dark site. Maybe that is an idea for next year, but it would be difficult to condition the spouse of my requirement to stay out all night at some remote site, when I can do it from my backyard in CT... hence that is a bridge to cross at some point...

So for your survey my data point is going to be woefully unrepresentative as I would say maybe 1x per year I may have an opportunity to experience dark skies... and that would probably have to be an 'event' like Stellaphane up in VT for instance...

I live in a red-orange zone, but I'm 40 miles/1 hour from dark gray and 160 miles/3.5 hours from a South central Oregon black zone. I'll most likely not drive up to the former more than a few times per year and maybe the latter once a year tops. It's more of a money issue than a time issue.

Stellafane is surely darker than anywhere in Connecticut, but it has lots of light pollution. The normal light-pollution atlas shows it in the yellow zone, but I think it's actually more like green.

That's the same as the "bad" sky in the original question -- the one that's just 1 hour from San Diego.

Even so, a visit to Stellafane will blow your mind wide open -- you will understand exactly why people are willing to drive long distances to find dark skies. Stellafane is still dark enough to see many, many dark lanes in the Milky Way -- though just a pale image of a true dark site.

I noted my trip to Natural Bridges above. I haven't been out since due to weather and travel. I think this a good thing as I might not be able to face the sky I normally have here too close on the heels of Bridges.

Even if you can't take a scope, you need to see the Milky Way from a black zone on a good night at some point. It's unbelievable and, literally, awesome.

I won't usually travel to a dark site. I did all that type of travelling when I was younger, and although I enjoyed it immensely at the time, now that I'm older I don't enjoy the packing, driving, unpacking, observing for all too short of a time, packing and driving home again in the wee hours. I still go occasionally, but once or twice a year at best - and this is to a green-blue zone... there are no really dark skies within reasonable distance.

I do, however, plan on traveling a good distance to a new home with dark skies when I'm fully retired in a few short years, God willing, and then I will travel no more.

Btw, just about anywhere that doesn't have "NJ" as it's state designation has darker skies than here, so I can only trade up!

Tonight the wife and I are going up to the dark skies to see some stars. We only have my binoculars to view with, but it'll be nice to see a full complement of stars for a change.

I have to drive for an hour to get to a yellow zone. I'm willing to do that any clear, moonless weekend. To get to a green zone I would need to drive 3 hours and I don't ever bother. If I could get to a black or grey zone in less than 4 or 5 hours I would do that every chance I had but I have no black or grey zones that close. As it is I drive 18 hours to the Nebraska Star Party once a year so I can have at least one week a year in a black zone.
