It was a joke.
Arizona officials responded to inquires after posting a blurry image of a roadway with a group of mysterious objects, with the caption: "We might have spotted a family of sasquatches on SR 260 near Heber this afternoon. What do you think?"
The picture, posted on New Year's Day, generated over 2,000 likes and was shared by more than 3,000 people.
"We were having a little fun," Tim Tait, a spokesman from the Arizona Department of Transportation, told Reuters. "People don't expect government officials to have a sense of humor, and we definitely have one."
Bigfoot is a legendary giant, hairy, ape-like beast that is variously known as Sasquatch, the Abominable Snowman, Yeti and other names. It supposedly lives in heavily forested or snowy mountains. Although most scientists don't believe in the beast's existence, decades of eyewitness reports, suggestive photos and stories have kept the legend alive.
Most of the nearly 1,000 comments on the agency's Facebook page appeared to go along with the joke, but a few defended their belief in the legend.
