PLYMOUTH – Three rows of circles, reminiscent of the wagon-wheel style of parking, are being created this week at the Baker Farm in Plymouth as Airstream enthusiasts pull in to celebrate the birthday of the trailers’ founder, Wally Byam.

Host Rob Baker said more than 90 of the quintessential silver bullet trailers from 30 states and several cities in Canada are expected to circle park for a weekend of events. About 175 adults and 55 children were registered to participate. The birthday bash begins Thursday and continues through Monday.

“We’ve been busy, busy here,” he said Wednesday as trailers were arriving. “The numbers are exceeding my expectations. I hope the weather does, too.”
