I drive about 35 one way, so I feel your pain. Obviously there are people who drive farther.
If you are wondering, it's entirely dependent on the club as to whether they will let you out, but you should be talking to them about this immediately.
There are no CAHA or USA Hockey rules that say you are entitled to move due to life circumstances.
Obviously they can't force you to pay, or your kid to play, but they can block you from moving anywhere else if they want, at least in the state. And to be fair, they may have left off other kids at tryouts in favor of your kid, so replacing your kid (depending on PDR issues, if it's a tier team) might cause a ripple effect that isn't great for everyone.
With that said, you should be talking to the coach and the club right now, before the season starts! Conversely, this could also mean that unless you can find a team that has roster spots open, it also might entail a drop down in division for your kid. You should also query any clubs that are playing at closer rinks to find out what the situation is with their teams.
