I've noticed lots of new chicks here lately, too--welcome to you all!
You might be right; it might be the whole "first day of school" feeling that is prompting people to start thinking about getting into shape.
I know that I love this time of year. It's still summery, but there are signs that fall is coming. When I was a kid, I would love getting off the school bus and going to get my horse out to ride. There was still plenty of light before dinner, and the cool air made my horse all frisky and fun. Ahhhh, those were the days!
