migalyto,
Thanks mate and I agree with you about the right hand river area. I think that will make for a nice small scene as well, perhaps a camping scene or something. I really haven't thought too much about the scenery in terms of what will go where other than the main Town and the possibility of a second smaller town in the S/E area near that river.
As for Trainworld ... I'll PM you re that.
George,
The only thing that I have planned for certain is the main town will occupy some the space N and NW of the yard, but not all of it. I think the majority of the right hand side of the layout will be rural and mountains. What I think I am going to do is get the track work down and then see what is what and what can go where, just play around with it.
