Add in where you are it helps, cannot say if the LP at Melbourne Aus is as bad as 8-9, and you may not even be there. When a question has a relevance to where you are a location helps. I cannot even look up what the LP maps indicates for you and at least then have the same data to work from.
In general LP maps seem to be based on population. Presumption being more people = more light. Reasonable bu fails to take into account smaller places and also terrain.
One place I visit has a reasonable town about 3 mile away, but there is a small rideg of hills between the 2 and so darker then indicated. 2 or 3 villages around me are on the LP maps but none actually have street lights. They are therefore actually dark, very dark.
How far you want to drive is a big aspect, time and distance. I travel only some 12-15 miles, and there are as dark or darker locations on the drive out but where I go is very convenient so I do the extra distance. In effect I will drive 12-15 but could as easily do 8-10. The closer location(s) are used by one local astro club a lot.
Finding one or two or three means a few visits to different areas, and checking places out. I use a nature reserve a lot, well the access road to it. So maybe look on a map for something similar. Easier is find a club and ask where they go and what they do.
Use an LP map as an indication. When I used to go to Cambridge the LP map was poor for the West side. The LP for the West of the M11 was bad, but everything stopped before the M11 and the West side was reasonable. Also they were installing the low intensity LED lights in the whole area, so agian the LP was lowered. The maps didn't take any of that into consideration. They just had a distribution based on X thousand people.
