»Mission and 24th / Valencia and 16th

BART stations drew violence yesterday: at 24th Street, a youth wielding a machete (!! -- where had he concealed it? down his baggy pants?) chased a man off a Razr Scootr and around a truck parked next to the McDonalds. Other youth, perhaps a third party to the fray, threw filled bottles of beer noisily into the street as they drove past.
A few hours later, at 16th Street, a lanky young man kept sticking his head in the corner store and hollering crude obscenities at the shop-keeper. Eventually he goaded the shop-keeper into coming out of the store and assailing him, while he pretended to dial 911. A tattooed man came along and very calmly separated the two, while the instigator kept screaming obscenities interspersed with an imaginary conversation with the police.
And to avoid it all, we hopped into a cab. The hackie told us that we could go anywhere except where those rambunctious Tiburon folk were: someone had just shot a tollbooth operator on the Golden Gate Bridge
