Changed plans

I'm supposed to be in Phoenix, observing a surgery today but they didn't have anything to show us and canceled. I was happy to have an extra day to pack (I hate packing so much) but I was looking forward to having company on the drive down (and claiming some mileage). I would also have booked an earlier flight if I'd know I had the afternoon free. I don't fly out until 11 tonight which means not getting to Ohio until ~10 tomorrow morning. I'm really hoping I can manage to sleep on the plane.
