2008 my brother was in his first summer camp for ISU football. I want to say it was the very first week and I picked him up to head to the Quad Cities for a Kanye West concert. The plan was to head to Moline, catch the show then drive back. Driving down, obviously you could see how high the rivers were, but we had no idea what we were in for. Driving into Moline I missed my exit and we ended up in a Tornado warning (Moline was also in a warning but they decided not to tell anyone in the arena. Remember, this is before smart phones.). Show up to the Mark of the Quad and it's raining a little, not a lot. When we came out of the show, there was 3 feet of rushing water running through the streets.
We ended up having to crash in Bettendorf then trying to trek back the next day. A 1.5 hour trip took us about 5 hours to get up to Cedar Rapids. Law enforcement blocking the flooded roads had absolutely no clue which ones were open, which were closed, and sent us on a goose chase. We ended up getting to Cedar Rapids safely and he only missed a day of summer workouts.
