SCG, I agree these places have to be seen in person if you can afford it. I am really looking forwards to the trip next spring. You won't need the flares and you can bring the GPS but it will probably only be taking up valuable battery space.
I told you most of the paths are well marked and I do know how to read a map.
We are going to have to discuss your Nikon though and try to figure out why you weren't getting good pics out of it. You should be.
