Today, I read a post that said, "Today, my dad told me about how when I was little I used to think it was someones job to change the stoplights. Apparently, I thought that there were guys under the road that had an elaborate set up of cameras viewing the street and they would change the stoplight colors manually by pushing little buttons. I believed this until I was 11. I find this to be an acceptable theory. MLIA" I'm glad I'm not the only one. MLIA.
