Back to your question on ceiling heights. How long is the lumber you use? I typically use 10' or 11' lengths and am always hitting my ceiling which is about 9.5' tall. My preference, and what I am putting in my shop I am building, is for just over 12'. That will provide room to move 12' tall boards when needed. Don't forget about light fixtures. They will hang down another 3-5 inches, depending on what you put use. If you only use 8' long boards, then a 10' ceiling should work, but still at some point you will still wish it was higher.
I am in love with Montana. For other states I have admiration, respect, recognition, even some affection, but with Montana it is love.... It seems to me that Montana is a great splash of grandeur....the mountains are the kind I would create if mountains were ever put on my agenda. Montana seems to me to be what a small boy would think Texas is like from hearing Texans. Montana has a spell on me. It is grandeur and warmth. Of all the states it is my favorite and my love.
