I wouldn't close the offroad track to run oval. You have a good customer base now with offroad and I'd hate to see all that hard work evaporate trying to push an oval track. If they can be set up at the same time that could be good, but closing down the offroad track to run oval you might hurt the newb turnouts at the expence of a few oval guys. Like I said before I'm willing to try it, but driving in circles doesn't seem nearly as exciting as offroad racing.
