About 20-30 minutes away depending on traffic.
It kind of goes both ways, though. It's definitely nice living in an NHL market with that big platform for the local team.
On the other hand, you can be just as hardcore of a fan for a minor-league or junior team, at a small fraction of the cost and with far better connection to the actual team and games. As much as I enjoy the NHL, I would love to have some of that small-league atmosphere back and that is not accessible at all. Even if I travel to see it elsewhere, it's missing the local familiarity which is the whole point of the experience.
Kind of like restaurants. It's great to have a Michelin-star restaurant in your city, but going there every night is impractical and weirdly unsatisfying compared to doing the same at a local mom&pop.
