This morning I got out the ladder and put the new exhaust pipe sections onto the greenhouse furnace. Now the drafting should be correct. Did the Krogers and Trader joe thing. Libbie and I went to the gas station together at Krogers so we could take advantage of our points which expire next week. We had 400 points which give us 40 cents off bringing the price per gallon to 3.19. COSM conrinues to workvery well tracking all our relevant sensor info. Dinner was turkey, salad, stuffing and broccoli. Yummy.
