I rode the 15m RRD all morning.
The kite tops out at about 25 or so.
It started off decent, then at about 8:30 it went to 20+, then tapered down to solid 15 or so for a couple hours and Donna and a bunch of others rode the 15 RRD.
By the time we left it was about 12.
It'll probably fill in again at 4.
