having seen videos on tv of folks that have attempted to drive through moving water,

and knowing how slick underwater rocks may be,

and agreeing with the folks' comments above,

and finding your comments and posts insightful and humorous and would be greatly missed - please don't drive through an unknown depth of rapidly moving water - if at all possible.

they can't be paying you enough.

and if you must go, keep the water below the body of the vehicle.
