Article content The 15-20 anticipated VW Westfalia buses taking part in tomorrow’s show are part of a regular group called Buses at Mariposa, and the organizers of the bus parade saw a natural fit with this year’s art theme. After meeting up in the Wal-Mart parking lot at 10:30, the buses will do a loop through the town near the waterfront and then park in various locations in the area. People are invited to check out the classic rides, see the interiors and talk to the owners. Many of the owners are musicians, notes Alcock, so a jam session is more than likely to break out.
