One of the few good post on the thread! A person doing this would be well advised to study the rivers around New York and keep a tidel chart as the rivers are tidal and you need the tide working with you so you can get as far up stream as possible. I would also advise that you have a cache somewhere up stream NY, NJ or CT as a goal so you can travel light and fast.
I’m curious where all the preppers are stowing their caches. Many claim they have hidden caches every few miles along their escape routes. Where? Private land? The idiot who starts digging a hole on my land might as well dig to 6 feet because that’s my land. Public parks? Those aren’t that close together and if the ranger caught you, you’d be in deep doodoo.
