Dry Wells is a (literal) ghost town somewhere in the American west.
The Richie Rich/Scooby-Doo Show
Shaggy Rogers, Scooby-Doo, and Scrappy-Doo got stranded there after Scrappy pulled the emergency brake on the train and got out to look around. Shaggy and Scooby went after him, and they all got left behind when the train moved out again. They found a hotel and checked in, but soon discovered the place was full of invisible ghosts.
