Guys,
I have not thought about it but why bring up and model something so painful?
I do not model hobos smoking but it is clear that they did!
Each of us is free to model realism in any way they like! What makes modeling interesting is leaving out the things you don't like about a particular memory or scene and even as you "change" your memory in this way you make it more idyllic and consequently more appealing and more of a draw to fine tune (except for those details).
We can all beam with pride when we point to our layouts, for my part, I want all my memories to be pleasant!
Even though death is as much a part of life I don't model a cemetary or a Funeral Parlor.
I suppose we all could point to tragic deaths in our own families from smoking.
Face it, realism has its place. But this is my boundary, one that I shall never cross.
Smoking in my opinion has claimed to much of my attention as it is. (Not On My Layout Yard!) NIMLY!
On my layout no one dies! Even though they frequently ride in or underneath my trains on the box cars.
Aren't you glad that you asked?
Mike
