Uh...do you have anything more than that?
That doesn't make much sense, and if you at least have seen the movie, or remember that scene, could you make it a little more sensible?
I don't know whether you are suggesting that people went outside and were turned to stone, if they left running from something like that, or if the road was turning people to stone, or whatever.
Check out Monolith Monsters. I don't really have anything to base that on, as I can't make out what you mean, but it at least has people being turned to stone in it.
