Many of the campgrounds now have websites, with pictures of the campground. When traveling, you may want to go to those sites and pick one that appears to have minimal tree cover. I know, you'll then be burning up in the sun - I guess that's the tradeoff. I have a roof mounted DirecTV autofinder dish, and often find myself blocked by trees. But then I'm usually perfectly happy with over-the-air stations. Helps if upon checkin you ask for a site with clear views to the southwest.
