This was the funniest thing I have ever seen. After we stopped at the Idaho Falls temple, we went to the falls, and this strange even was happening. Apparently everyone "adopts" a rubber duck and throws it into the falls and the first one to fall off wins a TRUCK! We were there for the after math when these guys were loading trucks up with the ducks they had fished out. yes. WIERD! But so fun to be around!
