I just got my Green Key Pass, $11. For 3 years, good deal!the ORV is the off road vehicle sticker, with it you can drive your truck on the beach in some of the county parks (smiths point, cupsogue, shinnecock east, and theres one in Montauk, all with off road beach access). It also allows you to park at other county parks over night for night fishing (like ponquogue beach parking
They wanted $35. for the OVR 1 year pass. I'll probably only use once. Do you have a camper? Than that would make sense.
