There is AC in the freight house, the gallery and the gift shop
Gift shop, restaurant & gallery are a/c. All the remaining buildings are not. This outdoor museum is filled with numerous acres of replicas of typical village buildings from late 1700s to early 1900s, so there is no a/c to replicate historical accuracy, except the 3 bldgs named.
90% of it is oitside, not air conditioned.
Gift shop, gallery, restroom all have AC, the rest do not. It's mainly how it used to be before AC was invited - natural air ☺️ Make sure to dress comfy and will need comfortable shoes because you will be walking a lot. Therefore, if your concern is AC, make sure the weather is cooler.
Not a good humidity level to go this week
There is air in the store and resturant and the museum
at least one of the old-time General Store setups has air conditioning. The bathrooms also have air conditioning. I'm not sure about any other buildings.
