Anyone with a fear of driving should try China! Traffic lights are merely a suggested behavior. and they have a heck of a lot of people over there so one less pedestrian isn't going to upset anyone....

As for all those volcanics Petra - depending on the age the ash could have come from Long Valley or Yellowstone - the bombs probably need a closer source... Can any of the magma you are looking at be intrusive? That was in a subduction area while the Farallon plate was subducting so a combination of intrusive and extrusive isn't surprising.
