Go to Rikers Island, build a barricade on the bridge to prevent walkers from coming on the island, there's buses and other large vehicles nearby since Rikers is right near LGA Airport. Also lot of food in the terminals, I would imagine the Airports shut down as soon as wildfire got out of hand so it shouldn't be overran
also loot the planes for some comfortable chairs, etc.
If that's not an option than an Island off of Long Island, a lot of them are connected to the Mainland with either a Bridge or a Ferry, Or a apartment building in Yonkers, they probably would be abandoned, low key city, etc.
Or even go to JFK and find a larger Jet to camp on, as long as you have Jetfuel you'll have a comfortable place to stay with Heat and A/C, etc.
I think you could survive in NY in a ZA long term as long as you don't go into Mantthan, plus NYers are stupid and delusional so there ego and pride have them getting
by walkers more often than other regions. So I doubt the Tri State would have many other survivors.
