I appreciate your replies and hope to hear from others as well to compare notes.
BTW Dick, I also appreciate your points about the true meaning of "Bonsai". The term as applied to Koi is an unfortunate misnomer that seems to have established itself. Having seen some wonderfully sculpted "Tree Art" I can understand your passion for the real thing
. Maybe one of these days I'll make it back to California for a family visit and take some pictures at a nearby Bhuddist Temple for you. There are still many old world Japanese practitioners of the art where I grew up.
