They have straw bale houses in Florida-- thats pretty humid. They have 100 year old straw bale houses in Nebraska still standing (Nebraska is where straw bale houses in the US got their start -- here is a link to the association there <a href="http://www.sustainableenterprises.com/fin/Services/links.htm)" target="_blank">http://www.sustainableenterprises.co...ces/links.htm)</a>. A properly sealed house can be built anywhere. The main problem is really "building codes" and also utility lines, and if you are not on a main road-- you need to build the road yourself, and repair it if it is washed out. Also mowing a fire break around the house, keeping the sucker-trees cut, burning off undergroth without burning down the house or the neighbors...Most country-dwellers I know have at least a tractor, a huge snow plow on a truck. Fire is a huge hazzard out there. You are very vehicle dependent. And a lot of these alternative homes are so far out that you need to be able to work from home. Then you are stuck living in "Nowhere Oklahoma" where nothing happens, driving 100 miles to the grocery store or to the doctors. It is very romantic to think of self-sufficiency in the country, but the reality is very different, especially where the need for money is concerned.
