Favorite thing: Deerfield was a significant part of my family history. If you are into history, this is a must stop. Just take in the whole village. It is 19th century New England. This is a great place to learn New England hertitage.
Go tubing on the Deerfield river.
There is a nice long 'lazy river' that ends near a state park.
Fondest memory: You can rent tire tubes from a local gas station and tube down the whole river. Hot weather,a few friends, and a backpack full of beer make this a great summer day adventure.
