Ehh i get where you're coming from, completely, but I don't think the market matters where its really at, as long as people show up and most importantly people tune in. Nascar can be successful with zero people in the stands as long as people tune in and watch the race on TV. Not to mention a Nascar event only takes place once maybe twice in that market, so i'm not sure really being in a big market is that big of a deal. Look at tracks in smaller cities like Martinsville, its a extremely small market for an event like that, but that event is one of the best in nascar. That's because of the history and the makeup of the track.
When nascar picked and moved from places like Wilkesboro and Rockingham, they left some of the soul of the sport behind.
What I can agree with though, is if they build different tracks around the country, they've got to make them unique. We have too many tracks that are similar, we need different things.
Part of why Wilksboro, Rockingham, and Darlington were so cool is because they were so different.
