Sure I will send them over with my social security number, mother's maiden name, bank passwords, and tax return info. What is your email address???
Seriously though I think just having the trails and intersections the most useful for GPS units. We poke around all the time and if we ever get turned around we can always look to see where the closest trail is and head to that. We did that in a whiteout about three years ago to get through some trees and find a road we had been looking for. If u don't already have maps and waypoints shoot me a PM.
