"There were a few injury's this year .. most at "Slippery" boat launch, I'll add warning to next years meet post."
No physical injury, but lost the camera to water damage as I slid down the ramp holding onto the boat, submerging the camera attached to my belt. Telephone survived.
Might also want to warn about wing dams, with the necessity to stay within the marked channel. Looking at a map of the the Mississippi River around Prescott with the many wing dams drawn in on both sides of the channel is scary.
