We don't exactly have much demand for blankets here in NM, but we're hauling Lucy to MT tomorrow and she still has her summer coat. The forecast is for anything from 12-34F en route and the stalls are not enclosed in a barn. We're going to have to stop and buy her a good blanket en route because nowhere around here even carries them. We have a nylon sheet that fits her, is it reasonable to assume that she'd need the same size in a heavy turnout blanket? The sheet is an 80 which seems pretty big in theory for a 15.2hh horse, but she's not a small lady.
