I would like to hear about them
@djsundog Not quite the same thing, but the Makermobile runs classes for kids and travels around British Columbia: http://www.makermobile.org
this is my towns official playbus. Often the bus itself is of interest to spotters as its usually a preserved service bus from about 20-30 years ago (but repainted in bright colours)
Old buses aren't expensive, but the driver *does* usually need a special type of driving license in most countries due to their size and/or the number of passengers (even if not strictly public transport), I think they get retired town drivers to volunteer for this.
