I was walking down on Market Street and saw this sign on the sidewalk. Here, there, turn right, make a left... very helpful arrows.I guess the City wants to make sure that visitors and locals don’t get lost. But, what’s up with the one pointing down? I’m local and I’m puzzled. Feel bad for out-of-towners… Hey folks, whatever you do, DO NOT go underground to the BART/Muni station and catch a ride. You will never make it to the ballpark this way.
