Living here since before the Canes and a very progressive place to be (compared to '89 when i got down here). These days there are a good amount of knowledgeable fans here, though do not expect them to be down low at games....have found very few. Most tend to hang up higher.
With that said, unscientifically, i would put them at about 30% of the fan base.
For some reason, the balance of local hockey fans seem to equate to a bizarre melding of minor league baseball, NASCAR and Robert Boucher Jr disciples.
