SoccerPop,
Trust me, I don't take anything about that decision that my son made, as criticism. There are some on this board that know the full dynamics of our personal situation at the time when I supported his decision. CHT has on many cases said, it should be the child's choice, and it was.
As for age, he was old enough to drive to practice.
As for the costs that you mention, physical, social and educational. Grades were better during the fall season when we had it, since we had the monitored time in the car. Social, trust me, he has managed just fine. I'm not sure of any difference with physical, but, we got into a routine, sleep in the afternoon on the way up, practice, study on the way home.
My wife and I both ejoyed our 1 on 1 time with our son on Thursday.
As you said, it is an individual situation, and for us, we still feel it was the best decision we made at the time.
If you want more details, PM.
