I would show your layout to model railroaders first since they may be able to invision what your building. Hopefully they will offer some suggestions after you explain your layout plans.
If you can preform operations, I say show 'em. If they are fussy about no scenery, they don't have any imagination anyway.
I'm beginning to realize that Windows 10 and sound decoders have a lot in common. There are so many things you have to change in order to get them to work the way you want.
At what stage to show family/friends your layout? Mine has no scenery and some structures yet. The floor is even worse: painted concrete. I'll put down foam mats on the floor after adding scenery. Such stages make the layout more appealing.
I plan to finish the layout/siding wiring this week. Once I know the locos run, is that a suitable stage to show off the layout, or should I wait until the scenery and floor is more pleasuing?
