Camping or renting a mountain cabin? If so, how do you go about it?
To find a campground that is more or less suitable for observing, I'd go to a website like David Lorentz Light Pollution Atlas and go for the ones that are in relatively dark locations. The nice thing about campgrounds is they usually have clearings where you have a reasonably unobstructed views (National Parks/Forests are great, but tree cover makes it tough to find good observing spots). One thing to keep in mind, I've observed in other Virginia state parks, and even if you're staying the night, you might want to check in with a ranger, since non-campsite areas often close at dusk. Even so, you may get a visit from a friendly ranger in a vehicle with bright lights.
For cabins, I've used Airbnb or Vrbo, combined with light pollution maps and Google maps satellite imaging to see if the property has clearings. Highland County Virginia is a worthwhile spot to consider: it's pretty dark, and there's comparatively little tree cover (also a beautiful place to visit, astronomy aside).
If you're fine roughing it, Highland Wildlife Preserve has dark skies and open horizons (primitive facilities and dispersed camping). Smoke Camp Knob in the Lake Buffalo Recreation area in the Monongahela National Forest is a terrific spot: 270 degrees of clear views to the horizon. It's remote, but accessible in any vehicle assuming no blowdowns, etc.
Attend star parties or astronomy gatherings? If so, are they local or destination events to which you travel? And how do you find out about such events?
Virginia has a number of fairly active clubs. I think the Northern Virginia club does frequent events at Sky Meadows (looks like there's one coming up this weekend). Many Virginia state parks host astronomy events which are listed on the park website https://www.dcr.virg...te-parks/events. Most clubs will list events on their website. I enjoy doing outreach/public observing - it's a great way to meet other astronomers, check out others' gear or troubleshoot mine, and to share astronomy with visitors. I usually follow my club website / email list for local events (I've never traveled to a destination star party). There's a Cloudy Nights forum for star parties: https://www.cloudyni...ws-conferences/.
