I went to a talk on the trams of Walthamstow this evening

On first pass, I thought this sentence referred to a talk that actually took place on a tram, which in turn reminded me of an event attached to last year's local folk festival in which Canadian musicans played sets on the city's commuter trains.

The very fact that I could be confused about this proves how close trams/streetcars are to my imagination and my heart. Ah, Toronto.
