We took my nephew to Brenton Point State Park down in Newport this afternoon to try out the kite he got for his birthday. I uploaded a few seconds of video to Vimeo -- check it out, but be warned Firefox doesn't like the clip, it should play fine in Explorer.
A word of advice if you go to a kite park: keep an eye on the guy with stunt kite. I got knocked clean off my feet by a guy who couldn't control his kite. I took it right in the ear and went down like a house of cards.
