Colorado used to have a set fine of $750 for illegal possession. Some of the well heeled non-resident hunters were starting to look at the fine as a reasonable "toll" to pay for a trophy elk. So the trophy definition was added to the regs with fines about ten times as high as what is listed for small bull elk or a cow elk. This seems to have have worked. Imagine coming home from a hunting trip and explaining to your sweet wife how we're are going to have to mortgage the house tocome up with $10K to pay the fines.
