There is only one heavily inhabited island in New York City harder to get to than Roosevelt Island, where Hillary Clinton will hold her campaign kickoff later this month. That island is Rikers Island.
I'm not the type to go looking for metaphors in things! I am not that type! I am merely here to offer insights as a New Yorker-American into the ins and outs of New York life. Including the details of Roosevelt Island.
First of all: Roosevelt Island is a cool place to visit. It used to house a smallpox quarantine center at its southern end, which is still in the process of being restored (after partially collapsing a few years back). It's got a bunch of new housing and a spectacularly painted public pool. But it is about as inconvenient a place to get to in New York as is conceivable.
There are three ways onto the island.
By car: The red line shows the one route onto the island by car. You have to get to Queens and make your way through back streets in an industrial area to do so. The Queensboro Bridge (or whatever it is called now that New Yorkers ignore) passes over the island, but has no outlets onto it. (It would be hard to do so, given how high the bridge is.)
What's left, then, is that little scroungy two-lane bridge from Queens, limiting how many people can get across it. But most people don't.
By train: Instead, they usually use the subway (the black line). Now, here is a secret about taking the subway to Roosevelt Island: It is terrible.
In order to get under the East River, the train tunnel is very deep underground, meaning you have to take about six escalators up to get to the surface. Maybe more, I haven't counted. I tried to take the stairs once, instead, and actually almost passed out. I'm not an athlete. But still.
By tram: The cool way to get to the island, the way that's mentioned in Hollywood Movies, is to take the newly refurbished tram, seen here in blue.
It holds maybe 20 people at a time and takes probably 10 minutes. It's beautiful! I recommend it to visitors. However, it is not mass transit in the sense of accommodating masses of people for rapid transit.
(Update: Twitter tram apologists point out that it theoretically holds 125 people. That 1) seems uncomfortable and 2) barely makes the trip more feasible for moving crowds across the river.)
I am not the type to find metaphors in things, as I said. I am just reporting that the Hillary Clinton campaign is launching from one of the least accessible parts of New York City. That is all I am doing here in this article. Nothing more.
Update: I added "inhabited" to the first sentence because Governor's Island -- where almost no one lives -- is indeed harder to get to.
