I know Cecil County in Md loves them and I believe its because they get a large car count. I agree many of them in my eyes are just race cars with tags. They are usually all the power added cars as you cant compete without a power adder with the ones I see run or one big costly N/A stroker.
Its cool if thats what the track likes but I could not afford to build one even if I wanted to. As for me I love the Nostalgia Super Stock racing myself and race in that when I do get to the track. But the street car shootouts at Cecil pack them in. Ron
