Ray Bradbury’s newest offering, Green Town, is a themed evening, a deft mix of fantasy and nostalgia set in the mythical town of Green Town, Illinois, probably suggested by Bradbury’s own birthplace, Waukegan. It’s an indeterminate time, somewhere around 1930 perhaps, in a Midwestern place where trees line streets surrounded by abundant flora, giving the locale its name. It’s a place where businesses are locally owned, and their proprietors are known to all, as are people’s neighbors. It’s a peaceful town until fantastic events begin to intrude.
