Ah, dirt and gravel roads.....now you're talking a subject that's near and dear to my heart.
Before I did any formal motorsports, I "raced" woods cars. Best race car training anyone could ever have.
Here's my first woods car (below). An old (1951) Austin A-40. Got it for $20 when I was 15 (1966) and drove it in the woods behind my folk's house. Some days we'd drive it 20 or 30 miles through the NJ Pine Barrens "fire lanes".
I still have the con-rod that escaped from that Austin engine sitting on my desk.
Even the police chief's kid had a "woods car" back then.
Although we had no insurance or licenses, the cops looked the other way because we kept the fire lanes open....important in the fire-prone Pine Barrens.
I had other woods cars including a Renault Daulphine, a Simca, a Hillman and a Ford Flatbed truck.
I did SCCA Pro-Rally later on, but that was more terrifying than fun. I'd love to have a go at Rallycross.
