My greatest use for GPS is finding residences and common places of interest while driving. Have no idea where an address is in the greater metro area? Type it into my little nuvi and I now have a guided route to get there. For finding myself in the big woods, or on top of the mountain, maybe not so much. Up at elk camp I much prefer orienteering my way around, first by studying a map of the area real good before I ever get there, then by identifying landmarks I can hopefully use from any location nearby, then by planning my hiking so I have a good idea where I am headed and what will be around me.
