Letters Log-Home Crafters Aren't a Vanishing Breed To the Editor: A comment on the short article "Log Home Demand Growing" (page 4, December 1985): I agree that the demand is increasing. The members of our Minnesota LogCrafter's Association, for which I edit the newsletter, are busier than ever. But no matter what the North American Log Home Council thinks, we who build with hand-peeled logs and scribe-fit each and every one without chinking are more common than "nationally... several dozen...handcrafters."
