Slowly but surely, my outs — the airports that I intended to be able to land at if need be, began to close up. First was Baton Rouge, as the overcast quickly engulfed the airport to IFR. I also noticed that the TAF had been amended to include IFR conditions for most of the remaining day. Next was New Orleans. Now the gravity of the situation began to take hold in my mind. What if everything closes up?
