We have kids museums in the US too. As a new parent I just discovered 2 nearby that have been here for decades. They have old donated vehicles like a police car, city bus, ambulances, or science stations, things like that. Things like plays exist, but it rural places they tend to be limited productions, either school or a traveling group. It may not make financial sense to have a play offered 6 nights/week all year in a small town, but a couple weekends throughout the year is common.
