After reading some of the threads on wood cribs, I was wondering what do you guys do if you still have a cord or two of wood left in the back of your crib at the end of the heating season. Do you cut new wood and stack it in front of the old stuff? It seems almost like you would need two cribs. Also what is the general opinion of the useful life of split and stacked wood left out in the weather (before it gets punky), 3-5 years?
