Not long after that double decker tour bus hit some electrical wires and sent some senior citizens to the hospital, another double-decker bus caught fire on Saturday while touring some folks around North Beach and Telegraph Hill.

The blaze began on the bus around 6 p.m. on Broadway between Davis and Front Streets, and everyone was evacuated and no one was injured. ABC 7 reports that the bus "exploded" into flames from the rear after witnesses reported hearing a loud boom. The burnt bus was left there to be towed.

It's unclear where on the bus or how the fire started, or why people ride these torture machines around town instead of just, like, taking cabs or bicycles or the F-line.

P.S. There's really not much to see once you get to Alamo Square, and there are plenty of prettily painted, better maintained Edwardians elsewhere.
