If you live in Boston, you should know about long island. If you lived in Boston for a while, you should know about the strange mysteries surrounding the island. For example, there are strange washed up creatures, a bridge where lots of suicides happen and countless haunted houses. But most importantly, it was a hot spot for alien abductions in the 60's, which is ironic because fallout feels like the 60's, and encounters. now to the theory.
In fallout 3 there is a man with a functional steamboat (if you have point lookout) that takes you to point lookout. That man once traveled all the way up to Boston and back, in fallout 4, he may come back to Boston. He should be able to take you to long island like he did with point lookout. In long island, you can see things like crashed alien ships, haunted houses and foggy shores.
