There's a very good Colorado ride report in the January edition of Rider, entitled "Black Canyon - A long look at a very deep ditch". The ride detailed in the article begins in Carbondale in central CO and ends at Four Corners. Looks like a spectacular ride...
Yes, 92 on the north side of Black Canyon of the Gunnison is spectacular. The vistas down into the canyon from the pull outs are amazing.
I didn't get around to taking 133 between Hotchkiss and Carbondale, but that road looks like it would be a blast. I was contemplating a "BIG DOG" ride from Golden that looped through there. Just over 500 miles to go from Golden to Sapinero, up to Hotchkiss to Carbondale, then back down through Aspen and Twin Lakes, then up to Leadville and back to Golden. Might be tough to make it in time for dinner... unless dinner is really late (and leave at dawn). At any rate, sure would like to go back through that area and check it out!
