Califon, NJ
As Wikipedia notes, "The town was to originally have been called California, but the name was shortened to Califon in order to fit on the welcome sign." However, local lore is that the person hired to paint the sign blew the money on booze and didn't have enough paint for the full name. Either way, it's Califon now.
My college roommate was from a dairy farm in Califon. There are still a few dairy farms in the area, but it's too hilly for other kinds of farms.
