NHRA-DR
This was on the back of an older mid-size Dodge pickup. NHRA, I am assuming is National Hot Rod Association. Then I will make the leap to DR being driver and not doctor. From the look of his vehicle all his money was going into his race car.
All of which remains me of two fellows I worked with 40 years ago. They got excited after going to a dirt track race and bought a race car. They entered a race. On the first turn of their first race a tie rod broke and the car slammed into the wall. Neither kid was mechanical, and the expense of fixing the car ended their racing career.
