log homes...
i have an opinion from living in one currently
personally i'd take an efficient, well insulated timber frame home over logs.
My sentiments exactly, after taking a class in log home building, building a log home and an office, as well as taking a class in timber framing. Two pieces of advice if you build a log building. 1.) Build the overhangs twice as long as you think you need (like 4') and 2.) get it at least 18 in. off the ground.
I'd rather have a cabin built from perfect block ICFs and interior timber framing. Don't forget the masonry heater. ;-{>8
