Help with Grafton Notch Road Sign

[walker]

While driving through Grafton Notch today I passed this road sign. I had to slam on the brakes, back up, and look at it again.
It's in the State forest, near the AT crossing.
I have absolutely NO IDEA what it means. Everything on the sign is stock. It has not been defaced by anyone. This is the way it came out of the sign shop.
Any ideas?????

PS I don't think it's warning people about someone hola-hooping in the road.

It's not stock, it's very well-done graffiti. It refers to the band "String Cheese Incident."

Yup

Yup...Thanks for the Heads up.. I guess I'm old enough now to be officially "out of the loop".
I just looked at their web site http://www.stringcheeseincident.com/, and presto, there's the road sign.
At least I don't have to loose sleep over it. Thanks
