The field at the Ridgefield Parks and Recreation facility. From Route 7, Turn onto CT-35/DANBURY RD. From the South, Valero gas station will be on your right at this turn. If you are heading North, you will pass Ace Tire and Professional Water Systems before coming to the Route 35 light.
After passing though the first set of lights, look for the Ridgefield Recreation Center sign on your right. There is only one field there, located to the left of the building and playground.
