Mark, We have finally warmed up above freezing here in the last week and a half, but prior to that we had not gotten above 32 for 5 weeks straight! Our lowest temp was only -10F but still that's cold. I live about 600' high than the townies do and very close to 4SD's altitude. Yet when the sun was shining there were plenty of Spam cans flying and a few RV's and the one Diamond Aircraft that's at the field.
Besides I thought cold dense air was better to fly in than that hot humid stuff you guys get. :) Fred Johnson Reno, NV
