has anyone ever thought about taking some of those pool floaty things that are foam with a hole in the middle of them and cutting them to fit over the racks to help your bike float...i was thinking about putting some of them on my racks to try and keep my racks from gettings scratched up when i go to push ppl out of holes...and also to help my bike float somewhat...but not sure if it will work or not not to mention i havent been in water deep enough yet to need them to help me float
