Does strike me as odd - dig up and relay a race track smaller also that a significant $$$ expenditure is on the cards with the current economic situation.
Maybe the cost won't be that huge, depends I suppose if they can get the new back straightaway in without having to demolish/ rebuild any infield infrastructure - maybe just lay a straightaway and reconfiguration of the turns?
Having said that, maybe the owners and/ or NASCAR have taken note that lots of racing fans like short tracks and there aren't many of them in the schedule these days - way too few in my books. I like the variety, so I'll be happy to see this come to fruition
