As I followed what you originally began with and John and Steve have added
the additional thoughts which occurred were the number of model train shows I have attended. Since a young age I attended with Dad, after he passed my Wife Carol attended before I had a layout. and now train friends. I spend time thinking of purposes of attending shows while looking over my layout. I think I attend shows now with the purpose to find scenery improvements. Many times new ideas are sparked by seeing tables full of merchandise large and small.
I hope the train shows never end.
During my work I had deadline after deadline year after year. Now I’m retired my goal is just to get to work on my layout, no deadlines.
