I was over long mynd way yesterday, went over the Shropshire hills. What a fantastic place that is, would be perfect to get the scopes out there. I am put off there though for 1 reason, the 2 ways you can drive up there are steep roads that have sheer drops at the side of you and no safety barriers. In the daytime it's not a problem but at night could prove lethal.
I've been looking at countryside areas around Wolverhampton on google maps and there seems to be a few decent looking areas, obviously not knowing what the light pollution is like but I think it would be worth investigating.
