While dining or walking on Emma Avenue in Springdale, you might notice some unusual sounds -- a distinct knocking, a door opening, boots on leaves and birds in the trees; chickens clucking; children laughing; dishes clinking; a microwave whirring on; a Spanish guitar beginning to play. Depending on the time of day, it might feel a bit ghostly, given that you don't see any doors opening or chickens nearby and not a cowboy boot in sight.
