In that case, I'll be doubly observant.
Urban, it was downtown on Auburn Ave, inbound (westbound)at the freeway junction. On a more positive note, I congratulate the city for finally repaving Edgewood Avenue, a designated bike route and former site of an apparent artillery attack. I must say, it is now absolutely pristine, although I haven't figured out why they painted a stick figure of a bicyclist in the parking lane.
I won't be bombing over any manholes from now on, though I think I usually avoid them anyway since the street has been patched/repaved so many times that manholes can be like deep ruts.
Similarly, I've noticed some pedestrian crosswalks in very old neighborhoods that have been restriped so many times that hitting them on my bike actually works like a sort of speed bump.
