I've got a Garmin Vista HCX. I would like to take a trip this upcoming Saturday that I've not done for about 7 years. Should be about 80 plus miles of pure dirt through a great part of Idaho. I have a pretty good idea of what it looks like on google earth now. I'd like to be able to lay down a track on that map (or something close) then upload it onto my GPS. I think that if I were to drop the money for their topo program I may be able to do it but honestly I don't have the money right now and I believe there has to be an easier and cheaper way to do it. Any ideas?
