I think I will go with Topo Us I like the detail with the contour lines etc. I already have NA Navigator and find there is no detail once you get off the beaten path. Perhaps I'm doing something wrong. Anyways I will buy Topo US and try and get everything loaded up. Shooting for departing North Van about Aug 21 and riding over to Roosville and picking up the CDR there. Have to be back to work in Vancouver Sept. 10. Gonna take my time and do some day hikes in Grand Teton and really check out the Colorado mountain towns and passes. Slab it home from southern Colorado. Thats the plan anyways. Thanks again I may post any more questions I have to you guys here.
