Since my family is moving to Hickory next summer, I shall watch your build with an intense interest and probably ask all kinds of stupid questions. Since I will be leaving my 1,000 foot radiant heated shop in NM, a heated shop is one of my big concerns in moving to your area. Once you have a nice shop, it is hard to imagine living without one.
Good luck and make sure to throw in details since I will be hanging onto this thread!
