I worked Country Stampede inside the Kentucky Speedway a couple of times a couple years back. They do have a couple Busch races a year (at least from what I was told), but the track sucks compared to all other Nextel Cup tracks I've seen.
I think local governments have a serious problem in thinking that if they build it they will come. Tons of cities are trying to build race tracks, sports stadiums and conference centers claiming as soon as it is built all these great things will happen. Truth is there are a limited number of races, sports teams, large conferences and worthwhile concerts. Besides who the hell wants to go to Sparta, Kentucky, the best thing about the place is the Casino on the other side of the border.
