A bunch of us sat on the barrels. About 85 degrees F.
We talked about something to put over it. Cob was mentioned. But the thing about cob is that it will make it take longer until the warmth gets to your butt. And then it will continue to be warm long after you have walked away - with nobody appreciating the warmth. Mud thought it might be best to leave the metal exposed although we did talk about some potential coverings. I suspect it might be years until it is covered with anything.
