The evidence is pretty lean as yet, but it *could* be true (though probably not).

Did A Meteor Cause A Brush Fire In New Hampshire?

In short, someone driving by claimed to have seen something meteor-like strike the mountain in roughly the place where there was later a fire. So… maybe.

Hmmm…

Of course, more boring explanations include a flare, fireworks, some other form of pyrotechnics and/or incendiary device; or nothing at all, the guy didn’t see anything relevant.
