Are there any Youth Hockey Parents out there that want to tell me what I've gotten myself into?

My youngest son (7 years) just had his first experience with REAL hockey after taking "Learn to Skate" last year and this year taking one 6 week course on "Learn to Play Hockey" at the YMCA in Oshkosh. Last night he got to practice with the Warbirds (Mites - not the big kids) and he loved it. So next Tuesday night is when they evaluate the kids to determine which team (by experience/skill set) they will be on.
