Austin - first off much respect for serving our country.

Secondly, you are right, I did ask. No hurt feelings here.
GT - Thats the whole thing. Who he is going with. When I was 18 my dad let me borrow his car, and take 2 of my 16 year old buddies to Glamis for 3 days. The difference is I had a lot more respect from my dad for my level of truthfullnes. Not saying I was always truthfull, who is? But I never wanted to let my dad down, not that my son intends to. But the parents of the other kids even wrote emergency medical notes. I promised my dad no beer and stuck to it! I never in my life had to sneek out of the house because if I was going to get drunk, even at 18 I would let my dad know how I was getting home or where I was staying. Just a matter of respect for him.
I think I will probably let him go, but let him know what he stands to lose by way of respect.
Sorry for the soapbox
