You can neither lie to a neighbourhood park, nor reason with it.

The second mode to deal with unsafe cities is to take refuge in vehicles. This is the technique practiced in the big wild-animal reservations of Africa, where tourists are warned to leave their cars under no circumstances until they reach a lodge. It is also the technique practiced in Los Angeles.

Why did I become a Canadian citizen? Not because I was rejecting being a U.S. citizen. At the time when I became a Canadian citizen, you couldn't be a dual citizen. Now you can.
