Looking great Phil. I think you'll be really glad you have that crawl space. I rarely need to go down into mine, but when I do, it sure is nice to have that access.
Sure helps when a couple of guys that know what they are doing show up to help for half a day. Fred P and my son finished the walls and helped throw the rafters up.
It will take some getting used to the tall ceiling as my current shop is less than seven feet
