Rainy Saturday trip with the boys to the Wenham Museum. It was actually our second trip there, but Sam was asleep the first time I traveled there. This time both boys were wide awake and ready to explore.There are quite a few model railroads at the museum. A local club operates multiple gauges in the basement, including 0-27 and a G-gauge layout featuring Thomas the Tank Engine. Every layout has the fun "Push-Button-To-Operate-Trains".

The main exhibit was examples of American folk toys. Almost every toy in the exhibit had a "TRY ME" version for the kids to play.
There is a family play area in the basement where kids can play dress-up, have snacks, run a pretend store, play in the pretend kitchen, read books, and play with toy trains.
Other exhibits included period doll houses, dolls, tea sets, puppets, masks, and a tin soldier collection. The museum is also connected to an 17th century New England house that you can tour. We were there for about 3-1/2 hours before hunger finally overcame their interest.

I was so impressed with the exhibits (and trains, of course) that I joined with a family membership.
Here is an upside down video of one of the layouts.
