Like so many national parks, Saratoga has a lot of excellent teaching materials online.
Not related to the trip, but as you’re teachers you might want to check this out.
The reason I liked that John Lindsay exhibit so much is that it was just as much about John Lindsay’s time (the Sixties) as it was about him. Remember the photo above? How would you use it in class?
Other interesting Lindsay things are available at the online version of that exhibit. I particularly like his commercials (scroll to bottom).
Here are two resources that came up in Wisconsin yesterday:
1. The Wisconsin Death Trip photo Flickr set.
2. Stan Schultz’s History 102 online class.
