Nice,
I love Colorado, I try to make it at least once a year.
I know you were in the Durango/Silverton/Ouray area because of the train and some of the mining pics, but where was your offroad driving? Was is the Alpine loop in that area?
I have spent a lot of time at the Taylor Park area with my ATV's, we would go and camp for a week and ride about 400 miles, to Aspen and down to Tin Cup ect on some pretty difficult and boulder laden trails. I will be up there in late August and I plan to rent a jeep for a day and do the Alpine loop (easier from what I have heard at least) or may do some of the more difficult stuff around Taylor Park.
Nice pics, it sure is hot here!
