It looks like the backstretch goes right through the buildings of Westside Storage, based on the horseshoe shaped clump of trees in the northwest of the old picture, literally right behind El Rodeo like awc#2 said.

Is this the Richmond track?

Bet that's an ELTO, huh Jim! Good to hear from you, you doin OK, or just hangin in? Bob

I don't know, but thats one of the coolest photos ever!

The picture of the #6 car was taken at Greenfield Indiana. Riley Park Tire is on that sight or close to it now. On the east side of Greenfield on the south side of US40.
