Uncle Josh bought this huge inner tube for the boys last winter thinking it would be good for sledding. It wasn't. It's just way too big. However, it's superb for bouncing. It's like a poor man's trampoline and has provided gobs of solid entertainment. Just today I re-inflated it and Art has all the sudden been able to bounce super high. And then I threw in a photo of Netta showing off her belly button.
