The large section of the middle of Pennsylvania where more cars are seen on lawns than the roads. Cousin sex is acceptable, and New Jersey license plates are generally despised.
**Note: The greater Harrisburg-York-Carlise region does not follow the general definition for Pennsyltucky. People there are civilized and own homes instead of trailers, yet don't carry the asshole persona you might find in Philadelphia. However, even here Jersey is despised. New Jersey sucks.
I drove 50 miles outside of Harrisburg, and some guy in Pennsyltucky made me squeal like a pig.
