DTA-
I am with you but I might point out that both my boys never practiced with their travel teams in the summer either. They were pitchers however.
To me, the biggest advantage of the travel teams is "fall baseball." Their travel team held winter workouts too, which was a real plus. Maybe some of the hitters practiced in the summer but for pitching work in the summer it was pretty much on our own - Dad or a lesson with someone.
"Give me fall baseball or give me death!"
