Major airport? hmm. Grand Junction, probably. Drive of about 60 miles or so. There is an airport at Moab, but I don't think that commercial airlines stop there. The vertical profile is on their website...but you have to hunt for it. I was planning for the skinny tire festival, but this sounds like a better time fit for me. (Oooh, a week of mountain biking, jeeping and road biking). And it probably wouldn't snow then, either.
Do they give points for vintage bikes/attire?
