You know you're living in San Francisco when...
...you get startled at 12:30 am by a band dressed like ninjas playing heavy metal with mobile amps and a drum kit, right in front of your place.
(No, this wasn't some strange delusion. I know it's real because I tracked down the contact info for Boz Scaggs, the nearby club co-owner, and sent him a "please, help" email.)
If they want to have Elvis Costello and Nick Lowe come over when they're in town and sing us bedtime songs, that's one thing... but secret ninja amplified heavy metal is just not right!
