Ken,
I have a bunch of old horse blankets and sleeping bags that I cover it with in the winter. I think it was the winter of 2010 or 2011 we went down to 19ยบ here.
We lowered it as close to the ground as we could can literally mounded blankets over it. "Normal" winters ie: like we had this year, I just covered it if we were going to have a freeze. Which was just a couple of times.
We used to back the pick up truck up underneath of it and back in to the aisle way of the barn and hang it from a rafter in there. Can't do it any more tho.
