Seen here totally shredding, a brave skater boy skitching on a corporate shuttle in San Francisco. And for those of you who don't know who or what a Marty McFly is: ugh, here you go.

SFist reader Regina Moore sent us these pics her savvy mom, Theresa, snapped while riding home from Stonestown. "My mom sent this along to me today, it's her trip home from the Trader Joe's in Stonestown. Check out who was on the road with her," Regina says, adding, "It cracks me up that my mom clearly came up upon him on Mercedes Way and took a photo from the moving car. Then she did a U turn and drove past him to park on Winston, facing him crossing Junipero Serra and then down on his way to cross 19th Ave to get to Stonestown."

That being said, we hope he survived. Of course. Way to go, dude.

This morning we ran north on Arguello to the Presidio. When we reached California Street, it struck us that there were no pedestrian signals at that intersection, which is rife with pedestrians, on a crowded bus line, and right near a couple of schools and a huge synagogue.

Thinking back, most of the intersections to Arguello don't have pedestrian flashers, with the exceptions of Fulton, Geary, and Clement. Every other intersection - including some big ones - just has the lights. We've written and read ad nauseum about the reasons that there are no pedestrian signals on 19th Avenue , and while we think it's stupid it at least makes some financial sense: nobody wants to take responsibility to pay for them, at least until someone dies.

Well, here's a chance to do something positive before someone gets hurt. Arguello is owned by the city, so there should be no conflicts with Caltrans. It's a street with quite a few pedestrians - we passed dozens on our run, and there were people waiting to cross at each corner of California - what's going on? Is there some secret kill-the-walkers cabal that operates on Arguello?
