Safari Hunter, your buddy is correct. Sullivan was denied an exhibitor booth at the upcoming convention in Reno.
This situation has been brewing for several years now. There seems to be an influential faction within SCI that believes Sullivan does not portray the image and/or adequately represent the values the organization is attempting to promote. I think you can bet that his egocentric videos had much to do with sinking him.
I don't know whether it's fair or not, but I do know I won't miss him.
If you really want to get a feel for what he is doing to "reinvigorate safari hunting in Africa," look at some of his clips on Utube and read the commentary in the comments sections below them. They are painting all of us in a pretty broad and pretty ugly light.
