I know, in theory, ETown could go back to drag racing after the 5 year contract is up, but NHRA knows for all practical purposes, a 5 year absence is a death sentence for that track. There is no way the NIMBYs are going to let that noise or the crowds back into their neighborhood after 5 years of relative peace (even though the MotoX and drifting events will continue). Buying ETown at this point would be prohibitively expensive because that contract will have to be satisfied first, then you would have to work out a purchase price on top of that. The way I see it, it doesn't matter that no cars have been parked there yet, as long as they pay (and that contract is in force) they can park whenever they want.
