I run up on this diddy searching for Gaffney Speedway in the June 5th,1955 Sunday morning Spartanburg Herald-Journal. The track was located on the south side of Old Racetrack Road just east of SC 150 about 4.2 miles SSW of town. (Aerial is 1966)
I ran across this one today, it is a fairly early shot. Notice no oval in turn 9, no 7B & no track support structures have been constructed as of yet.
Google Earth coords 37°58'13.41"N 78°12'22.48"W
Between US 250 & I-64 at the end of Jackson Heights Rd. 0.7 miles due east of Zion Crossroads
When I was young (5-8 y.o.) JIS was my home track, 1969-72. I have very few memories of it. I do remember the very low 1 rail armco guardrail down the backstretch that was very easy to go over. Also the treacherous "3 foot flat lip" on the frontstretch, that would suck you into the front wall if you got your right sides off the banking onto the flat.
Jackson was one bad fast joint. It and Winchester swapped the "Supermodified World record" regularly.
Lake Speed of NASCAR fame and former karting World Champion drove late model Camaros there.
The "track rule" was under caution, if you pit, you get your spot back in the lineup. Regardless of how many laps you were in for service as long as you were back on track before one to go. With all the crazy rules NASCRAP has implemented in the last few years maybe this will be next! LMAO 
Here is Zion Crossroad Speedway
