End of Summer?

Happy Labor day! The day many people consider the final day of summer. We expect it to be over 90F today and for days to follow so how can summer be over? The kids started into school a week and a half ago, so how can summer still be going? All the swimming pools in Colorado close this evening for the winter so it must be the end of summer. Linda noticed a tree or two turning yesterday while we were out running errands, so autumn must be here. I hope you all had great summers this year, BBQ's, swimming, bike rides, golfing, etc. and I expect that I'd best blow out my sprinklers this afternoon, after all, summer is over and it might freeze. ;-)
