I was expecting to read how you threw out the textbooks before landing, but then that would have been a serious test of balance. you should have put 16 gallons of water back there and one of your EWP's! you could get rated for fire fighting and make big bucks. sounds like my 2400nm trip to the round up may not win an award now.
