That might be fun. My college major was in Geography, my degree is in map making, I will put something together.
I grew up going skiing EVERY weekend (Colfax to Squaw Valley) and during the Winter there is ALWAYS traffic, so we learned the back roads. Some of them are only avail in the Summer, and some are only for 4wd vehicles with a little better than stock ground clearance. That spot the land rover attempted I have done in my XJ with 3" lift and 30" tires with a running start in 2wd. The land rover created these huge ruts in that spot though......may need more lift or bigger tires now as to not get high centered.
