Sounds like a lot of Hot air to me.. oh sorry thats just another falconer in the field...
Your on the plains of the U.S. of course it is going to be windy .. the birds fly in it. and you just learn how to set up your slips or work you fields accordingly .. just write it down as a learning exprience..
As Bob said as it got warmer the winds increase,, well maybe he didnt say that exactly .. but I would sure expect some winds .. to me average of 10-20 mpr per day...
