-check to see if there is a scheduled activity (story time, arts/craft…)
-pack a picnic lunch or snack. There is a park behind the museum. Picnic table, yes. Playground, no.
I had driven by this place 1,000 in the last 25 years. Wow totally enjoyed my visit. Spent 2 hours, easily could of done 3 or more hours. Many many photo opportunities. Very educational and inspiring.
