That is perhaps one of the most inspiring group of photos I've seen. I started leaning towards doing simply a mining operation, but now... I'm not so sure. Hey, bigsteel, I thought I'd share this with you too:
Chris Comport: Custom Model Building
If you look through the photos, you see the scratchbuilt sawmill. Kinda cartoon in one sense, but I really like how it fits more organically into the scene, and how it looks overall. I might have to borrow this design and build something like it.
Also: if anyone else has any other piccies of this layout, esp. the plan, please post them. I'd like to see the other side, where he has some log loading areas, but nothing is posted.
I'm starting to realize that what I want out there... I just can't find. So, I'm going to have to scratchbuild my mine and my mill.
Good luck and good progress!
p.s. I'm not really just following you around, and commenting on your stuff, though you give me good reason too!

I'm going to be asking for your opinions shortly.
