Excellent BTU rating for live oak - low sugar, high density, burn time long.
You guys don't have the wilt probelms yet - although there are centers reporting disease in the panhandle. Burning it as firewood does not release disease spores - transporting active disease could....simple rules for storage, available everywhere.
Locust and Hickory are best rated. I read a "cottonwood cordwood for fireplace" ad in the Albuquerque paper...makes me wonder about some people.
