Has anyone used this site? caltopo.com I use it extensively for my driving ,biking, paddling and hiking trips. Works on handhelds as well. I use it for trip planning. Only bad thing is you need to be linked in to the net for it to work. But I love it for looking at terrain and getting an idea of what I'm getting into. And you can create and print your own topo map. Any other free mapping options out there that actually work?
