I had a week to think about it on a recent little trip, and I decided to dive in fully with my plans to make my area Appalachian, or at least near-Appalachian (South-Eastern Ohio, Western Pennsylvania, North-East Kentucky, West Virginia - B&O country). Man, this requires a lot of trees! I've covered about 1/4 of the area to about 2/3 of the density I want. However, the process of making trees and shapes has been enjoyable. I've taken tons of advice and techniques from the Board here and tweaked them where needed. Thanks everyone! Here's the progress so far. I want to get the trees mostly in place before I move on to some smaller details around the scene.
