BS...great feeling and congrats to your son...not easy task to make team and even greater to make the travel squad and to get to play like he is going to. I am sure that he put a lot of hard work into it and now it shows. Go and have a great time watching him...remember that our kids don't want us to 'cheer' too much because it 'embarrass' them (in my case, I don't care with my son, I still cheer like crazy for the team).
Have a great time and drive carefully all the way and enjoy it. Time flies and these moments are really precious (not priceless! because they are still costing money!).
