Do a search on RAGBRAI - tons and tons of posts. I travel to Iowa frequently and there is a bit of a frenzy there among the riding community as RAGBRAI nears. I'm going to do 1 or 2 of the days one of these years before I really get too old, but seems to me day after day one has an awful lot of time on one's hands after riding unless you spend a lot of time at the rest/beer stops.
