How do you know?
Didn't I say don't ask? Sheesh some peoples kids!
Ok I'll tell you anyway, but don't tell anyone else. Besides the constant fight against salt corrosion from riding motocross bikes in a sand dredge fill site; one time I had my dads truck down at the beach and got it a little stuck right at the waterline you see, and with a little work, deflating the tires, and rocking the truck back and forth I got it unstuck.
Well about 9 months later when the folks took it in to have the brakes changed, the mechanic looked inside the rear drums and pointed out how somebody had the thing down at the beach because all the innards were just corroded beyond belief. Everytime I see one of those car commercials where they are driving on the beach I just cringe.
