I've been doing it for many, many years, but not too much in any single year. 12 years straight at last count, with at least another 6 some years under my belt prior to that. I'll admit it up front, I suck at it. With all those times down the track I have yet to win a race. I've won many rounds, but never the whole enchilada.
Funny thing about drag racing; I have a dedicated drag car. It is a bit tempermental, subject to variations in power and e.t. because of changes in atmosphere, is fairly quick and fast so I'm doing the chasing most the time, and sits around the vast majority of the year. My other cars that are not a purpose built drag cars are not as quick or fast so I'm usually being chased, vastly more consistent, less tempermental, more fun to drive, and have taken me deeper into rounds than the dedicated race car ever has, plus I get to drive them anytime the weather is nice.
I'm ditching the dedicated drag car....
