Mopars at the Rock is definitely not Carlisle.. In past years (2011 was literally a wash out) it was a fun little show. Heavy on the Mopar racing, a small swap meet and maybe a 60-80 car show. I always have fun there - but then again I live three miles from the track ... I think it will be interesting to see what, if any price the show pays for this year's antics.. I know a lot of people from out of the area were really upset over their refusal to cancel the spring attempt in the face of severe weather - and i can't say as I blame them.
Another all Mopar show is usually two weeks after the Rock in April at the Farmington Dragway near Winston-Salem, NC. It is a bit less race focused and has a lot bigger turnout for the swap meet and car show. Racing is still pretty active, albeit on an 1/8 miles track.
