I think most tracks make those decisions by 2 or 3 PM. Some earlier if the situation is obvious. I'm an hour and a piece away from Bloomington and plan to attend if they run, but I would not be surprised if they cancel out. A nice feature some tracks have is the text alert for cancellations or in some cases, affirmations that they are running. If you have texting on your mobile phone, both LPS and Gas City have that feature (see their websites), although Gas City obviously had a problem with their texting system on tonight's cancellation.
