Well, not all of them... But quite a few get out and about!
The off road biking types do this:
Helmet Cam at Crested Butte.
In Fruita at the Book Cliffs
The winter sports folks do a lot of this.
The ones who like to risk their necks do this .
My husband and I like to do this.
(Some of the roads-less-traveled we hope to see by jeep next Friday ~ as a late celebration of our 21st anniversary...)
