the lower portion of the track has been repaved. From what I was told yesterday by the head safety guy they did not pave X in the middle. Which to me sounds like dumb idea not to. supposevely there is a bit of lip coming from the x back onto the oval. haven't seen it myself yet though.
as far as dates. I believe the Miami can run events on the same date as orlando and it shouldn't effect anything.
Just look who goes to what events. Minus maybe 5 people the entire drivers list of WPB is all southern cats. Where as the OSW events now adays grab up orlando, cocoa, new symrna, daytona, lakeland, etc.... Should be plenty of people to make both events happen these days.
