Thanks for the suggestion of those magnet mounted fans. I bought a few Coleman magnet mounted tent fans at Wal-Mart and used them for about 4 of the nights on RAGBRAI. I used them in Glenwood, Shenandoah, Bloomfield and Mount Pleasant. Ear plugs were a must as well with all the late night crowd noise and music blaring into the wee hours. I had a bag of ear plugs and passed them out to fellow team members who were very thankful.
