Threads about general NASCAR news don't generally generate a lot of replies around here. The only racing thread that generated a lot of interest was
this controversial one, which started in February 2006 and was still getting replies late last year. So I guess the moral to the story is that we have a lot of people here who don't really have much interest in the sport, but will argue over it if given the chance.
For what it's worth, I was close to it in the 1990s and spent some weekends in the garage/pit areas. Many (or even most) of the people I knew in the sport dropped out, retired, or otherwise faded from the scene, though, and my interest faded along with it. I am still a casual observer, but that's about it.
