i think jimmy's idea would work the best (the others are great ideas too, so that noone gets their feelings hurt!) thicken/layer up the area where the rocks will be. if water already over the area you plan to put the stuff, take rocks that you (or a hired hand/teenager or whatever) can handle, wrap a bunch in the left over vinyl material, then set those down on your existing vinyl. then you can continue to add more on top of that, without injuring your main vinyl lining. mark
