I've heard of the book before, I'll make sure to pick it up.
Let's see, a quick google search turns up...Dave Johnston, Art Davidson, and Ray Genet in 1967, Naomi Uemura in 1970, Vern Tejas in 1988, Vladimir Ananich, Artur Testov, and Alex Nikiforov in 1998, also Masatoshi Kuriaki in 1998. Probably some others too. I know that's not all of them, so even if there's 20, I get the point that it's a short list. For some reason I was thinking it was more common and done most years. Hell, I'd still roll the dice on it if I ever thought that I was ready.
