i know someone who made a big pond with a pond liner, and after awhile 
the liner was punctured because deer were walking through it, and i 
guess the pressure of their weight concentrated on those little hooves 
was enough to bust the liner.  I think a thick-backed carpet underneath 
the whole thing might have prevented the problem.
