I've hardly been busking at all, what with the ridiculous temperatures (whaddya think this is, summer or something?) and the failure of whatever rain we do get to ameliorate said temperatures or humidity.
Exhibit A: Melted cats (note: we do have an air conditioned room. They do not generally choose to stay in it. I occasionally open the door and yell, "You're all stupid!" at them.)
However, I think this is relevant, since I do much of my summer busking near the Make Way for Ducklings statue. (found via Universal Hub)
