Why are people scared of the drag strip?

I drag raced at Moroso in FL years ago when I was young. It's too expensive. Drag racers have a lot of disposable income. I also don't have the time to pull engines out and repair stuff.
It cost thirty-five bucks to go to the test and tune. If you go to the dragstrip you're going to have to pull your engine out and repair stuff?
This sounds familiar....
