At Region Day a couple years ago, another chapter brought a turtle-shaped paddle. It was the greatest thing, and I wanted one so bad but I never could find one! I'm about to go get the saw out and see what I can do...
The biggest paddles I ever saw were the ones the SAE's used to give us. If you stood one on the floor, it would come almost up to your shoulder. That might not be big by other people's standards, but up until then the only paddles I had ever seen were just the regular kind you can order from the Greek Store.
