This weekend marked the final September NASCAR races for both New Hampshire Motor Speedway and Kentucky Speedway. Speedway Motorsports Inc. (the parent company of those tracks and several others...and Performance Racing Network, of course) got a big break in gaining the financial support of the city of Las Vegas to move the events to a second NASCAR date in 2018. The news is even bigger for Las Vegas Motor Speedway, because that weekend opens the 2018 NASCAR playoffs for the Monster Energy NASCAR Cup Series.
