Looks pretty good to me @mikerezny, great job. Its quite therapeutic isnt it. So long as the yeast is fresh, the bread will rise eventually regardless of the ambient temperature. Warmth will just speed it up. Keeping the outside a little moist to stop a skin forming. Ambient temp is always going to be a bigger issue in the bush than it is at home, and if its a bit coolish Ill put it in the vans sink on the rack, put boiled water in the bottom of the sink and a towel over it all to seal it up. You may have to be inventive to prop the towel up like a tent so it stays clear of the rising bread.
