That's a good point, Mark. At one time Mr. Gage's presentation went beyond the technical presentation into the politics of opium and the CIA, but his assistants prevailed upon him to keep the issue narrowly focused to appeal to architects and engineers and their admirers. They said that other people were covering that material very well, and Mr. Gage should stick to his knitting--and he did.
Of course those who had resource material outside of the technical bailiwick were perfectly free to distribute it at Mr. Gage's events, and I'd suggest that they would have even been welcomed as tablers, but I'm not aware that anyone ever took the opportunity.
I read the first 100 pages of Kevin Fenton's book and found it to be so disorganized and repetitive that I never got beyond that. I stopped at 100 pages with Ruppert's book too. Both of those books could find a readership if they only had conscientious editing.
It seems that Mr. Gage doesn't really do events anymore--the penetration of the internet into American and Canadian households makes this unnecessary.
How about somebody makes a video highlighting the Fenton and Ruppert material?
