Most of us model railways as a hobby for there own enjoyment, if they exhibit a layout it should be to show there modelling skill and to encourage and inspire others. If there are any trophies or awards to be won then that is a bonus but these days more and more clubs are struggling to get enough members together to run an exhibition let alone organise voting / judging, purchase or arranging return of trophies and finally the presentation.
Having been awarded trophies at exhibitions in the past on a few occasions I can't say I didn't find it gratifying, however the real bonus was being invited to show my layout and stock in the first place.
