It doesn't seem fair or smart or particularly nimble to write that the folks at Buntport are at it again. And yet: The folks at Buntport are at it again with their latest original play, "Best Town." By "it" I mean digging into a big bag of ideas, jokes, images, pop culture knick-knacks and historical archives to craft a witty, intellectually omnivorous bit of business that dares to be silly, too.
