Whenever I see this topic, I think of a conversation I had one day with a stranger. We were both waiting in a hotel lobby: he to join some family members to go to a wedding function and I to go to my son's next U18 tournament game.
He'd seen our players dressed for the game and asked what was going on. I explained that we were at East Cobb for a tournament. He smiled and told me that he'd raised 3 sons: two of whom were playing professional hockey and one who played pro baseball. After chuckling about the the continuous stream of weekend excursions, he looked me in the eye and said: "Don't ever add it up. It doesn't matter what it costs. You're helping your son live his dream." It didn't take long for me to reflect on his comment and agree...and I've never felt any differently.
