Nimrod found out that fraud pays better than competing in pro shows
That's why he promoted shows, and committed the fraud, ripping off Art Atwood and a few others (I want to say Darrem, but I think that was another show in Florida?) along the way.
He (maybe he is just the best known of the promoters) is the reason there is no Toronto Pro, and all contest promoters have to have all the money ahead of time in an account with no attachment to any of the promoters.
