Tough guys live in North Dakota. It actually wasnt bad today, about 5 degrees, the wind chill was cold tho....will finish up the floor tomorrow. After the floor is complete, we will be able to build the walls in the warmth of the garage. We are planning on putting a loft in it for storage, and a porch too...screened in. A/C in summer (yes it does get hot in the summer here)....now we will have no excuse to get all our planes flying!
