Canes definitely play more games there, including playoffs. PNC Arena is on NC State campus though and they have both women's and men's basketball, hockey, graduation ceremonies, etc. in the arena. However, place is decked out in Canes signage inside and out.
To piss off some of the people on this thread even more so, they actually have a whole store/kiosk inside the arena that is just Hartford Whalers gear. I grew up in CT and moved to NC (Hence my username) back in 2014. I personally love the Canes and have gone to a lot of games over the past 8 years. CT does a great job chasing away good things. Let's face it.
But hey, maybe the Danbury Thrashers will come back and be a thing. There's always that...
