i am 65 raising 4, and today I took the 13 yr old boy tubing down the creek. I didn't tube, but let him off and then drove a ways down the street and waited for him to drift by. but was very nervous about letting him do it . he is a good swimmer, but you know how it is, he only did it once then found some kids to play with and I was able to sit and look at quilting magazines. You just do things a little different when you get older and raise kids.
