Mopar Thunder September 3, 2010 - September 5, 2010 The Eleventh Annual Mopar Thunder takes place September 3-5 in Thunder Valley and will be the ultimate showcase for Mopar muscle. Returning to Bristol is the always-exciting Mopar vs. The World.  This special event takes place on Friday night and pits some of the fastest Mopars against all comers.  A Mopar car show will fill the Dragway grounds and offer fans a chance to view some of their favorites from years ago.  A visit to the swap meet and Manufacturers' Midway will give spectators and participants the opportunity to purchase the hard-to-find items they have been looking to buy. If you are Mopar maniac, be sure to visit Thunder Valley to take in all of the activities at Mopar Thunder.
