We picked up four of the mummy bags. Got two yesterday for the kids when they go to Cub/Scout camp, and went back and got a further two today. We've put a tent up in the garden for the weekend, so Richard and I put the sleeping bags out this afternoon, and we lay there in them, as we were unsure about mummy bags. We decided that they did not feel restrictive, so went and got two more, save taking the others out of hte camper when we use the tent.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
