Barberville, FL — (February 13, 2013) — Heavy rain moved over Volusia Speedway Park this afternoon, forcing track and series officials to cancel tonight’s action at the UNOH DIRTcar Nationals Presented by Summit Racing Equipment. If you were holding a ticket, its value can be exchanged for a ticket on one of the remaining 10 nights of action. We’ll be back on Thursday night with All Star Circuit of Champions Sprint Cars and DIRTcar UMP Modifieds.
