Nice trip
Some folks from the east don't have much of a clue about the mountain west. I remember years ago a usenet post regarding the closing of I-70 over a mtn pass and why everyone could not get anywhere. He suggested that folks just take the farm roads in the area!!
Anyway, I-25 and I-70 have many areas where bicyclists are allowed because there simply is no other way to get there.
Keep up the good work, jppe.
