Boyd, you may find this hard to believe, but it could be a blank screen (or all green) for all I care. I don't even own a working GPS right now. When it was working, I honestly never analyzed the terrain symbols. I have the waypoints in, and I just watch the tracking arrow. Before a trip I'll plan it on the computer using the photos in USA Photomaps...I'll print the photos out, and as I walk I'll use them for reference as to conditions ahead. I've gotten pretty good at reading the land ahead just by the way the light strikes off the vista, by what vegetation I can see, and the contrast on the photos that occurrs by vegetation type.Bob, I wonder if you would really be happiest with the real USGS scans?
