Midwest music sells used pianos and they are located at Clayton Road and Clarkson Road. During rush hour, the dealership is served by MetroBus routes 57X and 58X. Pretty soon, the bus will be served by MetroBus route 157X. It is walking distance from Manchester Road and it takes about 15 to 20 minutes to walk there from Manchester Road at Clarkson.
Now for the schedules for MetroBus route #57, go to metrostlouis.org. I emailed them suggesting that they have some sort of a small community shuttle bus utilizing either a van or a tricked out school bus to go along Clayton Road from like MO state 109 to the Ballas Transit Center or to Clayton, MO.
