Fenway, you are the man!
While in HS, behind the bleachers. Never where son could see us. One time while in Jupiter at PG tournies, with many coaches and scouts with radar guns, my husband would hide behind a tree.
At Clemson we always sat at first base side with parents and the same on the road but on third base side. We were a close group.
While in milb, we sat behind backstop only when son was pitching.
