Do you know how many sheets of ice there are in Orange County? I'd be willing to bet that it's pretty close to the number of rinks that Chilliwack has. Their just isn't a ton of room for growth here.
(I think we have between 6-8...and those aren't exclusively for hockey use.)
In Pittsburgh, I started playing ice hockey when I was in 8th grade in 1992, the year the Pens won their 2nd cup. At the time, there were only a handful of rinks in the area.
Since then, many of those rinks have added a 2nd or even 3rd sheet of ice, and serveral new multi-rink facilities have been built just to handle the demand.
Not to mention that the talent level and intensity of Varsity hockey has increased dramatically since I've played. (I now coach, so I know) The University of Pittsburgh hockey team went from a virtual non-entity to now being an ACHA D-I team with a D-III team. And if you go to a Pens game today, you'll see that the arena is completely filled with people in their 20s and 30s.
All of this can be directly attributed to those great teams of the 90s. And with Sidney Crosby in Pittsburgh for the next 20 years (hopefully), it's just going to keep getting better and better here.
So don't underestimate the impact some great NHL hockey can have on a sport within a community.
In fact, I would say that this would be a great time for an entrepreneur to invest in a new rink in Anaheim.
