stocks of old growth timber suitable for guitars & such are really premium items anymore. The guy who is mining the lake for sunken timber is making a fortune. I presume that 'alternate' materials will continue to be developed, but your grandchildren will play thru the nose for 'real' old wooden guitars with that 'special' quality.

(One of the reasons we have those #*&&%%$@! plastic grocery bags now, is that the long, unbroken fibers necessary for strength came from older trees, and now they cant buy any appreciable quantity...)
