Jeff not sure where you are reading your results or possibly there is an error in the results on the website? Or maybe you didn't have enough coffee this morning?

Has the following:

Race 1 Blue:
JC/Sarah 14
Mike Easton/Mckenzie Wilson 16
Taylor/Catherine 20

Race 2 Blue:
Easton/Wilson 11
Newberry/Casey 17
Taylor/Catherine 18

Mike it means the wind shifted/died enough after the race started to cancel racing.

Personally I figured JC/Sarah would be a bit further ahead on the U.S leader board. Sounds like its really light air sailing though and things are a little iffy. Bigger spreads to come I suspect as the breeze builds.
