I couldn't tell what you were camping in but here are some fairly local cgs. KOA in Fort Mill SC which is just over the state line --- a little south of Charlotte on I-77. High Rock Lake CG in Lexington at I-85 exit 91 --- the speedway is I-85 exit 49. There is also one at Linwood NC but I don't know the name of it. There is an rv resort on Rte 150 near Terrell but again I don't know the name. You might want to check RVParkReviews.com on the last two. I hope you have an enjoyable time while in the area. Razoo's at Concord Mills, which is just down the road from the speedway, has great Cajun food.
