I'm with Joe, this is a huge reason I moved out of a fucking neighborhood.
Our old neighbors decided their family needed to all move in with them. Six cars, the boat, a motorcycle, a 30' camper, and a garage full of useless shit. The street parking in front of our house was theirs. The street parking in front of their house was theirs. The street parking in front of their neighbor's houses were theirs.
At least with our collection, we had two cars in the garage and four in the driveway. Two directly in front or house, if available, if we had the boat at the house.
I can see his frustration, but this is why I sold my suburban house and moved the fuck to the country.
