At our post season banquet each year the booster club has presented the coaches with gift certificates to a resturant or a round of golf. It has never been an issue and is taken as it is meant, to show our appreciation for all the time they put in with our kids. The coaches won't take Joe Torres job anytime soon but they do the best they can and they try to do the right things for the kids. That's about all I can ask for.
In the four years junior has been playing at the high shcool I have never witnessed any politics or bad feelings parents might have towards each other or any of the kids. I know some parents wish their son would have played more but I haven't seen any parent to parent pettiness. I guess I've been lucky to have been around realitively sane parents all these years.
Games are always pleasant with everyone cheering for the team and individual kids.
