Looks like one of my favorite sites finally sold out. Topozone.com is now part of Trails.com! Hurray! <insert sarcasm here>. You can now access the Topomap for 14 days via a free trial. After that it is $50 per year. All I want is to look at plain old scanned topomaps. I don't need them in 3D or any other fancy tools.
