Ditto for me, Mike. Except that the first forum I found online was Water Gardening Magazine's forum, then KoiVet, NI and Koi Bito in that order.
Several members of the Louisville Koi Club were my first mentors, Charles Phelps, Dick Weidner and Jack O'Daniel. Met another member of the Louisville club after seeing him post some comments on NI, Mike Pfeffer, who has been very generous in sharing koi knowledge with me from the time I was a little grasshopper in this endeavor.
I just noticed as I read back through what I've typed that all 4 of those mentioned above have made trips to Japan through their interest in koi.
Other mentors are almost too numerous to mention because I have taken the time to travel and visit so many of them. Of notable mention.... I spent a great day at Thom Blishoks. What a fantastic, interesting man and arguably one of the most knowledgeable in the hobby. Have made a couple trips down to visit Brady Brandwood and he has been here to visit us. Man! What koi knowledge that guy has accumulated between his ears and in his eyes!
There are so many people in this hobby with an attitude of helping others who are coming up in it. I guess we can all relate to being where the people are who ask us questions now because we were there once ourselves, too.
So thanks Charles and Dick and Jack and Mike and every other Tom, Dick and Harry that I bothered when I didn't know what I was doing and was trying to find out!
