Yeah, I first heard about it when Cabela's pulled out. That alone should have been a huge deal, since they're arguably the biggest dog on the hunting & fishing block. (Bass Pro being the other contender.)
Apparently, the show's organizer, Reed Enterprises, also does the same job, contracted by NSSF, for the SHOT show. NSSF has announced that they are 'reconsidering' the arrangement, and Reed will probably lose that gig as well.
