All of that is in a MARES rolling luggage/backpack. WITH LOCKS ON ALL POCKETS AND ZIPPERS. Nothing is ever stolen.
Of course your DAN insurance too, and C-Card.
I did have to pay $100 overweight going to Key Largo, and another time on Mexicana (will never fly them again!). CONTINENTAL is the most diver friendly and flying First Class they let you take 3 bags at 70 lbs. each!
