If you think about, say, the pressures put on the ground from an overweight kinda lady on high heels, and the weight-taking part of most high heels is alot less than a square inch, you are maybe thinking about, I don't know, 120 kilos per square inch??
(Lady is 60 kilos (please correct me if this is grossly inaccurate) and heel of shoe is 1/2 square inches (again, please correct me if this is wrong))
And the weight on each stand leg would be 105 kilos, not including fish, gravel etc.
