In most road construction sites there's guys doing work, and then there's one guy whose sole purpose is to stand there with a baton and wave traffic by. Most ppl are fully aware that construction means to go around. Well, I was surprised that this site had a robot to stand there and do this job. I thought they were being efficient - NOPE. Turns out there's still a guy, with a baton, to watch the machine and still wave ppl on. What the point of the robot is beyond me.

Ha, too funny. I'm a Sign Waver and some call us "human directionals", I wonder if this will render this title obsolete.
