The Dept. of Parks and Recreation currently provides free WiFi connections in select areas of parks throughout the boroughs. It's a chance to swap your indoor computer space for the great outdoors. Follow this link for directions on how to locate an active area and connect to the network.
In addition to the Parks map, NYCwireless, a non-profit organization providing internet access, has an online searchable map that has many other free WiFi spots throughout the city.
