Leo,
Thanks for the response! and tips and ideas. I know Van Buren county! I am a WMU grad. I traveled up to the north woods for these, Oscoda county. I agree, older trees need to be addded to the mix and I have no doubt I will find some as I know some great areas now. I have another balsam fir that fits sizing wise, and I do have elms and hornbeam as well, though I think I would keep it conifer, but who knows. Ill probably stick a jack or 2 in the mix, maybe a red pine, keep it up north themed, If i do end up combining all as one. The search for the right container will likely be a long one I imagine. I think some mini ferns will work their way into the final composition because there is so much of it up there, and personally, I just like ferns.
