On the bowling alley idea:
According to the equipment manufacturer, you need a population of about 40,000 to support a 24 lane bowling alley. Ridgefield has about 24,000 residents.
Interesting stats here:

Interesting if you google map "Bowling Alley, CT", it shows about 30 bowling alleys, with a big hole right in our area.
