A thought provoking question Peter.
Do folk feel proud when they've achieved something easy or something difficult?
Would I be prouder having built successfully, that is in my personal opinion, the opinion of my peers and the opinion of members and visitors if I'd built on sand or clay or something else like say hard rock or volcanic ash?
Would I be prouder if I'd built successfull (per above definition) on flat, featureless land, in a desert, in a swamp, in a forest, in an area of high rainfall, in an area of low or nearly nil rainfall, in the tropics, in a temperate climate, in a cold climate, where it's normally windy or normally calm, dry or humid, next the sea, inland, in hilly or even semi-mountainous terrain?
Would I be prouder if I'd built with a big budget or a small budget? With limited access to men and machinery or with lots of men and lots of big machines. With leaving the native top soil in place or stripping, sandcapping, replacing it. With full irrigation or with limited irrigation. Where the drainage is natural in soil or gradient or where the natural drainage is pretty much non-existant.
Just few things to consider. There will be more.
For my part I think I'd be prouder having built successfully somewhere awkward or unorthodox.
