There typically 5-6 cars parked in the yard of this house daily. How many adults can live in a 3 br 1 ba house? I guess at least 6 ... is there a violation for yard parking. The neighbor next to them was cited for having ONE car parked on the side of their driveway. They graveled out a section to comply. Why aren't these other folks being cited?
