I looked at speed suits but they are like $200 or more. NO way!
I went to the local outdoor store and found a new TYR fastback suit on sale for 30% off. I need a new one anyway- so at least I'll *look* shiny and new.
Maybe I'll just glue the butt cheeks of the suit to my bum and then fill that area with air. Instant flotaion (although my butt surely has enough fat to keep it afloat on it's own).
