Took the (in)famous Chinatown bus for the first time today, to see a friend finishing a stint in Philadelphia. ('Dafia' is - I think - Cantonese for the City of Brotherly Love.) I've not spent much time in Phillie - never more than a day - but every time I am hit by the thought that it's the perfect size for a city, just the right mix of old and new. And we happened into a gallery where a painting really took my fancy. It's by an artist known as SPEL.
