Kiln dried vs Natural seasoning

[Paul]

Richard
I've seen Steinway's "lumber yard". They stack thousands of board feet of
rough sawn lumber out side and let it season according to their specs per
species.  Their claim is that the lumber is given a change to "relax" and
"adjust" to the change from a tree to a board. The EMC is to high for
production, so further drying-in kilns-is necessary. I "wood" like to know
how others dry lumber.
