Underdog Racing on the road
|
This is how I took both cars around the US this last summer. I took an 8700 mile trip around the US and raced in Texas, Azizona and California.
|
|
This is when I was in the 16s and still driving the dragrace YUGO to the track and it was at this time I used it for my DAILY DRIVER.
|
|
This is at Atco Raceway one of the last times I drove it to the track. After this it became a "Tow Bar Special".
