Here's a link to find local accommodations in this area. There's not a single motel in Greenfield itself (I TOLD you I live in the sticks! :-)) but there are several within a few miles' drive.
Greenfield, TN... it is only 590 miles from my house in Plano, TX. That is closer than my parents house in El Paso, TX. That is one thing about Texas, when I lived in El Paso it was a shorter drive to Los Angeles than to Houston. There are plenty of Mopars in Texas, they are just spread out. It seems like every second Mopar is in SoCal.
Midlothian, TX: now that is pretty much local for me. I drove through there once going between Dallas and 281 on my way to Austin.
Mopars seem pretty scarce. A-bodys are hardly represented at the shows around here. But, when I went to the dragstrip for the Mopar day in Denton there were plenty of A-bodies and it was one of the few times I had to tell people which '68 Barracuda was mine. Wow! Definately no lack of representation at the dragstrip.
