It’s interesting how in the RAGBRAI shop they say that the jerseys are a “pre-order item” and they won’t ship until the last week of March but if you don’t want to wait, you can go to Scheels in West Des Moines and buy them right now for $65. Interesting.
Check with the Iowa Great Lakes Chamber of Commerce or the “U of O campus store” (The Three Brothers) in Milford. They have an annual “University of Okoboji Cycling Classic” at the end of June and the U of O Oktoberfest Bike Tour (in September, natcherly) and all participants receive T-shirts; don’t know but jerseys might have been available for additional cost.
Or if you put a bug in their ear soon enough they may consider going with Jersey-Ts (do they still make those?) instead of run-of-the-mill T-shirts.
