I think that only the regional rec centers have it. Think you need to log in with golf pin # that you get at closing.
Also, many restaurants at the town squares have free wifi.
Also, if you have Comcast (Xfinity) back at home for internet service, you'll be able to connect to any "xfinitywifi" hotspot that you're near for free. There are a lot of them.

Other major internet providers like AT&T also have wifi hotspots.
