This is the island:
We have a cottage in the bay, and I've been going to the island since I was a few years old. I put a geocache on it.
It's hostile. The beach is all large rock, and 4 miles from the mainland, you can get stuck out there in bad weather.
We watched this NYT reported being shuttled out there. My uncle had related losing his underwear in the surf the day before to the reporter, and I hoped that would make it into this article.
