Larry Forman lives in Battlement Mesa; sometimes, outside his house, he smells sulphur.

“[It’s] like rotten cabbage or something like that. It kind of reminds you of a wet dog, but it’s not exactly like a wet dog,” he said.

He doesn’t know what it is, but thinks it’s coming from the natural gas well down the hill from his house. Forman studied the distance and concluded it’s 765 feet, close enough that a good golfer could easily drive a ball from his back yard and land it near the well pad.
