Don't forget to post your location and opinions of wimps in the South!
I said, "10 - 20." That's my wimp-out point, but I'm a little crazy, so don't count me out, ever! (Of course, it almost never gets that cold down here! )
My eyeballs cry on the downhills when it's cold. I'm not crying, but you knew that, didn't you?
Sorry! Here are the Celsius temperatures, as converted from Frigginheit, er, Fahrenheit:
50F to 60F / 10C to 15.5C
40F to 50F / 4.4C to 10C
30F to 40F / -1.1C to 4.4C
20F to 30F / -6.7C to -1.1C
10F to 20F / -12.2C to -6.7C
0F to 10F / -17.8C to -12.2C
Below this, there are no exact conversions, but I'd still like to meet your Mama!
