Been busy with other projects. BUT thought I'd stop by and pitch up a track plan to acquaint you with what I've got going on with my Ozark layout. Hopefully, you'll be able to see these photos (via clicking/enlarging) well enough (forum shrinks pictures) to understand the plan.

The upper level:
The upper right is the same on both plans, so that's where you connect the two plans.
All fer now!
