The RAGBRAI trailer will have this year’s logo on the front with map on the back. However, lots of vendors will have countless varieties for you to choose from. I wander the expo until I find the shirt I like best.
Used to be that all the shops on the ride — Bike World, World of Bikes, Europa, Yankee Pedaller, and all the others — got permission from the Register to use the name, the logo, and the Register-drawn map on their shirts if they wanted to, since they were also providing the mechanical support services along the road. Some went with the “official” map, others went with their own version, meaning that the maps on some shirts indicated both overnight and pass-thru towns; other only indicated overnight towns; and some just drew a jagged line across an outline map of the state of Iowa. In addition, daily mileage may or may not have been included.
Personally, I always liked the ones that had the pass-thru towns marked as well as the overnights, as well as the daily mileages, so I would take the time to wander past the official RAGBRAI supporting shops in the overnight towns during the week and look them all over before I made my selections. I advise you to do the same. -”BB”-
