1. When you've just spent the weekend with your layout at a "big" show with a group of modelling mates who humour you (for about 48 hours), do anything you ask to make the show successful and ridicule you mercilessly.
2. You get a lot of "thank you - I really like your layout"s from a very wide range of visitors who stand and watch you play trains as well as lots of gratitude for the advice and help you can offer.
3. Oh...and the crowds are three deep in front of your fiddle yard watching others who have "made it" playing in the sand on Fen End Pit - the rather excellent layout next door...
That'll do me.
