Since you are "looking for wood to cook with" and you live in Richmond, Tx, just get some local pecan wood to use and it will turn out ok. Not sure why you would want to baby sit it all night, when you could turn the heat up to around 275 to 300 and have it ready in about 1/3 of the time. It will still be as good or better without the long cook times.
Of course, if you are looking for some long fire tending and some overnight fellowship with some friends, then ignore my suggestions. :biggrin1:
