We have been having swim practice in the outside pool since March (Alabama). This week we have had the huge jet sprayers going to keep us cool. The heat hasn't been terrible - the killer has been the sun. Every time we do any stroke or drill on our backs we just about go blind.
Yeah I went swimming today and the water was so warm it was not refreshing or cooling at all. I think I should have just wetted myself down with the waterhose instead.
