MYTHICAL, USA - - another KBE project to enjoy

Good point.  I'll have to reach out to some contacts and see if it turns up.  Hope it's not hiding in Caribou, no one would ever find it there.

Gumbo -- The link you have for the Perryville, MD billboard is incorrect and leads to the Rocky Mount one. Here's the one for Perryville: https://twitter.com/MatthewRay1/status/1038187820345634817

The link for Glasgow, DE's doesn't work when I click it for some reason, but I was still able to find & access that same post natively in Instagram when I checked the #MythicalUSA tags. Maybe try re-copying and pasting the link to see if that fixes something.

@Jonny - Yeah, that'll definitely make it harder to find. But Vermont has a similar billboard ban and the GMM ad was spotted on a bus instead...Hawaii and Alaska also have restrictions and the ad was on the side of a building and inside an airport, respectively. So it has to be somewhere in Maine!

Maine's billboard ban probably explains why one hasn't been found there....https://www.nrcm.org/nrcm-success-stories/billboard-ban-protecting-...

Now down to only two [2] missing billboards.

A town with 751 population that I suppose was named after this relatively large plover bird, and not a roadside dining hoofed ruminant mammal of the family Cervidae with slow reflexes.

#MythicalUSA fun facts & trivia . . .

(with 46/50 sites reporting)

• THREE of these things are not like the others . . . have you figured out which billboards have a different image? Hint: 

• how small is "small town" USA?

• with all the humorous town name selections, why pick Dardanelle, Arkansas? Rumor has it may have something to do with the local high school mascot - - the SAND LIZARDS

• ARIZONA - while several #MythicalUSA hunters report finding billboards that are technically not located within the boundaries of the named town, but "just down the road" a bit (i.e., Buies Creek sign is about 100 yards across the Lillington border), this state's allocation was placed across the state line in Needles, California. Was it by accident or purposefully put there? According to Wikipedia, the isolated city of Needles has long debated on whether or not to secede from San Bernardino County (CA) and join itself to neighboring Mohave County (NV). Proposals to change states would require approval from the United States Congress and both state legislatures.

• WEED HEIGHTS, NV is an unincorporated community in Lyon County, Nevada, USA. The Anaconda Copper Company built the town for mine employees to reside in 1952; mining operations ceased in 1978 and the entire property has been sold a few times since then. Today the entire residential community is privately owned and operated as a rental community and RV park. Because it is not a census designated place ("CDP") participating in the US Census, it's residents are counted as part of adjacent Yerington, AZ (population 3,048).
