I plan on spending around an extra 4 days in Co & UT,that's why I purchased those other maps and books. I don't regret buying the books,but for this trip I don't think they were necessary.
Here's two pictures of the White Rim Trail in UT that most people ride. I wanted to show you what it looked like in the National Geographic map,and then the Moab East or West Trails map.
First the Nat. Geo Map
now the moab map
Both great in their own way,can't go wrong with either one,but I think I'm leaning towards the Moab map.
