You can be warm at the fire in the fall - get this

Started using these last year after reading about them in Trailer Life. Put some charcoal briquettes in your fire and when they ash over put 3 or 4 in a coffee can and place under your chair. Its not enough heat to burn your chair but it sure takes the chill out. If you don`t have charcoal just use some of the hot coals and I almost forgot, no matter how good his intensions may be don`t let your rum drinking friend get one ready for you. But furnaces don`t knock them till you them.
