Well, sure, it may affect things for the first few weeks after  
"seasoning". But not years down the road. The method of "seasoning",  
or drying, will have no effect on the stability of wood years after  
the fact. Well, assuming the drying process didn't result in the wood  
splintering to pieces.....
