Pioneer Square, 1st Ave S at S Main St

57) You could walk around Pioneer Square for years and never notice this tiny little post office on 1st Ave S at S Main Street. It would, however, be difficult to overlook this fine box stationed outside. I’m embarrassed, though, to admit that while posing for this shot, I didn’t even notice that funky gray lockbox stuck on the side. I have absolutely no idea what that is, but I wish I had given it a closer look.
