Some valuable information, but if you're interested in going to any of these places, make sure you fact-check. For a recent revision of this book, there are a few errors that I found and it's possible there are more. (For example: the Detroit Zoo hasn't had snowy owls in its Arctic Ring of Life exhibit since shortly after it first opened. Also, the buses back across the Mackinac Bridge aren't usually free when doing the Labor Day Bridge Walk, but cost a few dollars.) ( )
