I'll tell you the market that is out of control (not that it's the best fit for this) but the 20-30 year old market for organized sports is insane in CT. For any of the younger crowd on here, you know what I'm talking about. What started as WAKA (World Adult Kickball Association), yes I swear this is a real thing...has now turned into Club WAKA where they have leagues with hundred and hundreds of participants every night of the week playing kickball, flag football, sand volleyball, dodgeball, etc. etc. You name it and they're doing it. I'm still amazed that WAKA hasn't built some kind of complex in CT where they can house all of these events. It's huge and seems to be growing and from what I understand pretty much every session of every sport offered "sells out" and there's limited availability.
Now I don't see how this helps two 6,000 seat stadiums, but I'm just bringing up that if there is a market in CT that's strong, this is it. Honestly, WAKA would probably kill it with some kind of complex like the one that used to be in Vernon (only for baseball/softball) because they could use fields for all of their different sports.
