Black Cap #10 (aka "help me I am trapped under a garage door!") Location: 18th @ Harrison. The Mission. So why do you think there are so many black knit caps in the mission? My friend Melvin said "Because a guy just did a B&E and he was tearing off his mask and wool cap as he ran!" Jed said "Ninjas. Definitely Ninjas."Thoughts? Opinions?
