On the rare occasions that we temps don't flag, we either get to follow around a full timer and try to not be annoying all day, or we get cut loose and given some random endless assignment just to keep us busy and out of the way.
Last week, my fellow flagger Bo and I were given the task of weedeating bridges, guardrails, and jersey barriers on several roads in the middle of nowhere. Now say what you want, but the novelty of weedeating really starts to wear off around the fourteenth or fifteenth hour. The high point of this was that we cleared around a covered bridge that I had no idea was even there.
I also saw a lizard.
