Busking at the airport
I have no patience for bureaucracies that proclaim that they are unable to innovate. It's not that they are unable to do so, it's that they don't want to do so.
The other day as I walked through SFO, I heard live music. Live! Looking over, there was Bart Davenport and his band, playing real good for free. Probably not for free, actually, but collecting plenty of tips in the box out front. They sold a lot of CDs too.
What a great venue. What a service (for Bart, for me, for the airport).
Go ahead, do something impossible.
