Tim, this happened to us the other year at the PAS Oval National's. We seen on Friday that Saturday looked like a wash-out so we called the airport to see what it would cost to change our flight to Monday morning. It would have cost an extra 100 dollars per flight ticket, extra night for the hotel, extra day for the rent-a-car, another day of eating out and the loss of a day's work for Karen and I. So to stay for one race (even though it was the big one), it would have cost us about 1000 dollars, so to answer your question:2:, we came home.....
