Yes, attending the PBR in order to get verifiable measureables and videos, in order to send to coaches, is a smart move. (In my opinion)
I wouldn't sweat the college far from home thing. I have a 27 year old son and a 16 year old. Typically when kids go off to college, you'll be lucky if they spend summers with you in their freshman/sophomore years (less likely for ballplayers as they'll be playing summer ball somewhere). After that you'll see them for a week at Christmas, or even just a few days, maybe they'll spend much of winter break with you, but even then they aren't exactly sitting at home playing Yatzee with Mom & Dad. They'll be out hanging with friends and/or girlfriends most of the time. It is tough, trust me, but it is just part of growing up. And it doesn't really matter if they are an hour away or 7 hours away.
Encourage them to attend the school that is best for them, that will set them up for life. You won't regret that.
So true. My eldest does his best to spend some "quality time" with my wife and I when he comes home, then he's out the door, or in his room with the door closed.
He's a great kid, so I'm not complaining.
