OK, I sat down last night with my friend, who is, let's just say, a big dude in the Parks & Beaches division of the Town of Oyster Bay. The official word is that bicycles ARE NOT and WILL NOT BE allowed beyond the snack bar area at the west end of TOBAY's parking lot, where the bikeway extension now ends.
That kills MY buzz, as I will never leave my bike in a rack to walk to the beach or to one of the restaurants. I guess leaning my bike virtually against my table at the Seafood Shack the first weekend was too good to be true.
Anyway, I also suggested that the snack bar stock some tubes and patch kits. He suggested that I contact "H" (the owner of the concessions and all the restaurants) directly with that idea.
