Yes, my son plays on one. Be prepared, depending on the team it may not be cheap. Plus you have to pay for travel. We try to stay with a couple of hours but we do go as far as Missouri and Georgia.
A few travel teams recruited my youngest son and he and my wife and I said no thanks. He plays little league and middle school baseball and middle school basketball. He said I want time to rest and not get burned out, we agreed and you are right travel ball is expensive and time consuming.
