1) The threat of hypothermia, (we never saw the sun, and it was drizzling a lot, then the wind came up.)
2) Being left alone to video everything for the last 4 (of 6) hours with someone else's equipment. (and still have to take still pics)
3) Watching the car lurch up down sideways and the boss's wife commenting "At least adrenaline keeps you warm"
4) Getting a phone call in the middle of all this mayhem "Honey, the computer's acting up" which turned out to be a dying (now dead) keyboard. It's good to have friends who have extra Mac keyboards to loan!
