PHOENIX (AP) -- An Arizona agency's posting about Bigfoot is leaving its mark on social media. The Arizona Department of Transportation Facebook post from Jan. 1 reads: "We might have spotted a family of sasquatches on SR 260 near Heber this afternoon. What do you think?" Accompanying it is a couple of traffic camera photos showing a blurry cluster of figures on the side of the road. As of Tuesday, it had been shared more than 3,700 times and had nearly 1,000 comments. Spokesman Tom Herrmann says his agency tries to drive traffic to its Twitter account using humor -- a strategy that has helped them gain nearly 52,000 followers. The mysterious figures haven't budged in days, leading Herrmann to believe they're something a lot more down-to-Earth than the original post suggests: shrubbery.
