We (and by that, I mean me) decided it would be a good idea to go to a Retro on Roscoe on a 100 degree day. Kids didn't notice initially - hence the joy as they jumped. The guy working the harness for Ryan pulled it up and made him hang there. Took him a bit to even realize! He was so focused on the surface below planning out his next jump ... He didn't really he was just hanging there ;)
