A small, boring town in upstate New York (or downstate, depending on your point of view. It's an hour away from the city.) It is mostly suburbs, apart from Main Street (where almost everything is closed down) and some rural parts in Mountainville. One of the only interests in Cornwall is sports. The mascot for the schools is, inexplicably, the dragon. Most younger people living in Cornwall will say that they can't wait to get out if it, as there is hardly anything at all to do.
Despite its proximity to Newburgh, there are really no gangs or violence outside of teenage "mischief" and the Maplehurst Inn (home to crazy homeless people, one might say).
It's a solidly middle-class town, but in Cornwall-on-Hudson, it's pretty high-class. It's divided into Cornwall, the Village of Cornwall, Cornwall-on-Hudson (which is along the Hudson river), and Mountainville. It's close to New Windsor, Washingtonville, Salisbury Mills, West Point, and Newburgh.

Person 2: Uh, Cornwall?
Person 1: ...
Person 2: It's between Newburgh and West Point.
Person 2: Ohhh...
Person 1: Yeah. It sucks.
