Claim:
A method for converting a watertight carrying case into a portable desk, comprising the steps of: using a carrying case having a body with a horizontal bottom side; front, rear, left and right sides projecting upwardly from said bottom side; and a horizontal top lid pivotably connected to said body for opening and closing said carrying case, wherein each of said sides and top lid has an interior surface and an exterior surface; wherein the exterior surface of said rear side defines first and second spaced-apart projections extending rearwardly, each of said first and second spaced-apart projections having an outer surface; and wherein said top lid portion pivots relative to the body from a closed position, in which the interior surfaces of the bottom, front, rear, left and right sides and top lid define a watertight interior compartment, to an open position, in which the interior surfaces are exposed; and mounting a mounting bracket on the exterior surface of said case without piercing through any interior surface of the case so as to keep the interior compartment watertight when the case is in the closed position, said step of mounting said mounting bracket including extending first and second mounting portions of said mounting bracket along the outer surfaces of said first and second spaced-apart projections, respectively, forming horizontally-oriented openings through the first and second spaced-apart projections; and extending a fastener through a horizontally-oriented opening that has been formed in the first projection and through a corresponding horizontally-oriented opening in the first mounting portion and extending a fastener through another horizontally-oriented opening that has been formed in the second projection and through a corresponding horizontally-oriented opening in the second mounting portion to secure the mounting bracket to the case.
