Several clubs had complained about the cost on 3 different continents, these are not well to do rich people, but many folks wanted to have him speak. So it's a deal with the devil so to speak. Translator, and another 1-2 other people to come along to help. Photo books that had little to do with aquariums.......I do not know.......I did not pay the bill, only heard what was stated. I have no reason to not believe them. It's a big draw, much like the contest is. So is worthwhile for many. We as hobbyists want to build the hobby. This is one way to do that. Same with the contest. In some respects, I do not blame him/ADA. In person and with good communication, I think a lot of this stuff is a non issue, but on the web....this stuff can be blown out of proportion at times......... But the complaints were in person about those cost and they did not appear reflective of such ill/bad behavior. Still, I did not pay that bill, so who knows.
