There are streetlights, but it's not that well lit. What is curious about this is that the area is wide open, so the guard, if he was in his usual spot (that's where he was sitting at 8:30 last night when I drove by), would have seen the assailant from quite a ways off, and had plenty of time to observe events and get backup before going it alone. This is a port, and all types of undesirables filter through the area, not to mention late-night partiers coming from nearby Quintana beach.
I'm not quite ready to jump on the terrorist bandwagon over this. However, next time I go by in my white pickup with limo tint on the windows, I think I'll roll through the stop sign.......
