I don't know about Grantsville, Bear Lake, or Utah Lake, but DC is not 50 degrees, at least not close to shore at the Charleston Bridge launch; it measured 65 this afternoon. Why the huge discrepancy between my measurement and that posted on the internet? No idea! Could it be that my temperature probe is grossly out of calibration? Don't think so, as I just compared it with a mercury lab thermometer at 20C (68F, the lowest mark on the lab thermometer) and the probe was only high by about 0.3 degree C ( 0.5 degrees F). And, it doesn't feel like 50; John Dubock and a visitor from Long Beach were both sailing in shorties and doing fine.
