Last night I got to see the Toronto Raptors play the Boston Celtics at the Air Canada Centre. I don’t know why a Darwinian struggle over control of a big orange ball is so entertaining, but it really is. The Raptors won, earning the excited hoots of Torontonians. Then we descended lots of steps to lower ground, searched for a way out, and received half-a-dozen free bags of Doritos as we exited.
