Just wondering...how cold is too cold to play out doors? Couple weeks ago one of my tennis buddies and I played after work 27 degrees.....was pretty miserable to be honest. I'm a little to old to be out there runnin' around in sub freezing temps. We did play 2 of 3...but niether of us really enjoyed it. LOL....And I won't do it again. I'm way past the whole BS macho thing.
