lookn2it back a long time ago when I played softball we had practice like that and the temperature went up to over 100 degrees. My mom told the coach that if he didnot have the sense enough to get the kids out of that weather she had the sense enough to be a mom and take me and my sister home. In about 5 minutes he let the whole team go and we didnot practice again for about 5 days due to the heat. Sometimes I guess parents have to voice thier concerns to coaches. My daughter is 4 and I would do and say exactly what my mom did if it ever happened even if it meant her getting kicked off the team. I was on either cnn or msnbc that a 17 yo very athletic track star died yesterday close to Chattanooga with a heat stroke. Sports isnot more important than life. My opinon on the subject and I hope your sons coach sees the error of his ways before he gets a kid sick or worse.
