Hi all,
We are headed to Stow, MA for a week from the midwest, and have two kids in tow. 5 and 1 year olds. We will have a rental car available to us, and are looking for things to do while we aren't visiting with family. Right now on the radar is the Maynard Discovery Museum, the Worcester EcoTarium, and the Franklin Children's Museum.

Mostly interested in burning some energy, but I'm highly motivated to avoid children's museums that are basically cavernous-but-otherwise-empty dumping grounds for school field trips. I find that in my area it is the smaller museums that are generally more interesting.

Thanks in advance!
