We have the first tee time on Saturdays at my club. It's great for the summer when it's really hot but for the first hour or so in the winter it can be brutal and sometimes we have hour and a half frost delays. The cold is one reason my handicap goes up in the winter (already 9.2 currently from a low of 7.5 this summer).

I now wear pants even in the summer. Two fewer things to slather with sunscreen and the new technical fabric pants are quite cool
