Floating— What Do You Float On? [PICTURES]

With the weather warming up the floating season is quickly approaching.  What is your preferred item to float on?  I've floated on Air mattress', Tubes, and rafts.  Possibly one of the hardest but most hilarious items to float on/with, is a blow up cow!

Wherever you are floating please be safe!  Always get a DD and make sure you float on approved floating devices!  I don't think cows are the best choice---

This Cow is MISSING!  Sadly someone stole her at the tailgates.  If you've seen this cow let me know!
