I took the kids to the park attached to the school after kindergarten ended. We only had one crash into a soccer player at his recess when D wasn't at his kite instead of in front. These are Justice League aka Batman kites, look at 'em go. OK, we did spend some time on the ground, but eventually they got pretty high, at least in comparison to the boys.
Okay they could definitely be higher, but not bad for a couple little guys.
For more high stuff - head on over to PhotoHunt.
