Yeah, the locomotives are definitely one of the similar examples of backwoods Maine obscura that came to mind.

I do appreciate that the NMW and other concerned organizations responded to the huge uptick in interest in the locomotives by establishing a drivable dirt road with a nice trailhead and hiking path--but that increased accessibility does come with the liability you describe.

I get why people post stuff.

I think it's nice that folks find something really cool and want to share it. I know I have gotten that same impulse.

However, yes--in those moments, it's really important to remember that the internet doesn't need to know about everything, and you might inadvertently have a really negative impact on a place by publishing it online.
