Fort and Cass was where I usually ran into Sir Sir. He used to pretend talk on the payphone in the lobby at the Comerica Bank building for reasons I can not explain, other than maybe it was loitering cover from the pesky blue blazer lobby security.
Speaking of vagrants, there seem to be less of them now in the CBD. Or less obnoxious ones, like Sir Sir. Why? Bubonic plague? Gentrification? Economic recovery?
