Geez ..... I don't know but if you've ever seen gasoline become set on fire, it all happens like very, very fast.
Just looking at the photos on the webcam, the Sept 1, 2018 shows a single red fire extinguisher in the center of the dock, positioned at the white post.
And, looking at today's May 11, 2019 photo, there is no fire extinguisher ..... so there's no fire extinguisher .... there ..... at the gas dock. How safe is that?

Seems like some gasoline stations have a fire suppression system but maybe that's just in Massachusetts, Maine, Vermont, Connecticut, Rhode Island, New York, and New Jersey and probably is not required in New Hampshire. But, what the heck, for like $25 at Walmart you can get a larger than usual fire extinguisher that could come in very handy, sometime.
Maybe Flightcraft and The Dive can set up a 'go fund me page' and raise the needed $25 to get a decently large fire extinguisher for their gas dock?
