I haven't wanted to post this because no point giving anyone ideas but when I was a young girl my family would go up to the Adirondacks to a particular little town that has eight - yes 8 - year round residents and which is inaccessible a large part of the year, you can only get there via boat or going over the ice, they only had one phone when we would go there, at the general store/inn/bar/restaurant (yes it's all one), there is no police department, no schools, no nothing. It's just a handful of people most of the time.
I hope upon hope they didn't manage to get there because nobody would ever find them I don't think, unless they were so terrible at being outdoors that they gave themselves up. Pretty much every cabin up there is seasonal.

"Beaver River is
a hamlet that is six tenths of a mile square, at the east end of Stillwater Reservoir, in the town of Webb in Herkimer County, New York. The hamlet is surrounded by the Adirondack Park. The hamlet has
a year-round population of eight, that increases during the summer as many people have camps in this wilderness area. There are 125 private properties, and three commercial businesses. No roads lead to the hamlet; it is accessible only by hiking, rail car or boat in the summer and by snowmobile, snowshoes or cross country skis in the winter. There is no electrical service. The town is named for the Beaver River. The New York Central Railroad right of way, on the National Register of Historic Places passes through the hamlet; an existing bunkhouse is a part of the historic property."
ETA oh gosh we always went by boat, we'd have to be on the water like 45 minutes before we even reached there. But apparently there's train service!! ugh!!!
