"You could say the same for the bonsai themselves, and quite a few people would agree with you. Most of them non-bonsai people. Many of them their spouses"
Uh, how much cash do you have on hand?
I didn't say owning a few of them was a bad thing ;-), just that owning ALL of them would be quite useless for the money expended. ALL, or more than a few dozen ;-) of them is flushing $$ down the crapper. That's what a few good lessons from a master bonsai person would cost, or the price an airline ticket to Japan.
When is money better spent--on old books (by the way, I have over 200 old bonsai books and a few Kokufu albums, as well as some other Japanese albums from more obscure shows, so I am familiar with the obsession for collecting old books) or on lessons, or --Heaven forbid--an actual bonsai?
