The Leeches - S1-E4
Factual error: When David Vincent lands at the airport, a sign there says, "Welcome to San Diego." When Vincent exits the airport, it says, "Maricopa Airport." There is a Maricopa in California, but the episode takes place in Arizona, as indicated by the license plates on the cars and mentioning the city of Tucson close to the town the episode takes place in.
The Leeches - S1-E4
Other mistake: David Vincent arrives at the airport and a sign says "Welcome to San Diego", but the episode takes place in Arizona and references Arizona-related locales: Tucson, Maricopa County, etc.
