I had forgotten the Ellie Island bridge, is that still cruelly fenced off in Liberty State Park? Always looked quite substantial. I have poked that fence, so I may be on a database somewhere, but then I’ve pogoed between Canada and the US at Point Roberts. It’s probably a minefield today, but back then the border was nothing more than fluorescent yellow painted kerbstones and signs telling you to report to the US Customs station and declare your nefarious intent to stray south of the 49th parallel.
Not really sure it’s going to dent the ferry company profits, you have to get to NJ first and then walk.
You probably know that Ellis Island ‘belongs’ to both NY and NJ, which makes it the most unusual island in the New York Bay, the subject of a long running territorial dispute that fortunately didn’t result in open warfare (though NJ did invade in 1956*). The original bit of island belongs to NY, all the infill parts to NJ (well, jurisdictionally, so check the law in each state before choosing where to break it). Conceivably, you could steal something from the gift shop, stray between jurisdictions and then have to be chased down by the FBI. I’ve not tried this, but I like to think that it might happen.
A guy I knew bought a gas station in Jersey City to convert to a home. Turned into decade plus of hydrocarbon-based nightmares, but is now worth a bazillion dollars to escaping Manhattanites and is, I have to admit, far cooler than my house (whose only distinction is being on a steep hill, which it might slide down one day, and our living room is level with the top of our neighbours’ roof.)
The only other pedestrian bridge I can think of in NY is Ward’s Island. Not very exiting though, other than say you’ve done it. Greenpoint is very gentrified now, but I mostly know NYC from the 90s when it had a bit more of an, erm, rustic texture. I have actually walked everywhere in NYC from top to the bottom. Walking places is my thing.
Museum exhibits. I look at the thing first, then read, then look again. Although an inveterate reader of things, I sometimes like exhibits to go without explanation (the majority of life doesn't come with notice boards). I never do that ‘audio tour’ nonsense. Things are best discovered. Either that or ignorance is to be embraced.
*led by the then Mayor of Jersey City, part publicity stunt, part that he wanted the current immigration museum and NY wanted to dump all its homeless there. He also banned rock and roll. I don’t know why I know these things, there’s probably an information board on Ellis Island.
Edit: actually, I checked and it was resolved by the Supreme Court in 1998, when I was a resident alien, so possibly the news.
