I think most states study the state history in fourth grade. I'm not sure why, but that was the pattern in Oregon and even when I was a little girl in Colorado. There was another "Michigan" field trip for Zhen's class and I went along for the morning session... They call it a "Voyageur Encampment"....but they dont' seem to stick all that well to that theme. This Native American re-enactor really did a lovely job, though. I hung on his every word.
