I'm not normally a Clyde but my winter weight creeps up close every year and I wasn't able to lose it in time (or yet) this year so I did RAGBRAI as a barely qualified Clyde this year. The seventh year in a row for me and only health or death would make me miss it. It's a great ride, it's great fun, and if you do it right even waiting in line is fun! Any ride is dangerous but many comments above are highly exaggerated. Pay attention to what's going on around you, give the other riders plenty of room when passing, and you'll be fine.
