Not at the corporate level. We have had some through this site. Kentucky Lake and Champlain if I remember. I wasn't here for Champlain and KL didn't fit into my schedule but I have fished with a LOT of members here. Wouldn't be against organizing one though.
you would think with Nitro being made here in MO and the Big BPS here. (also the popularity) One of the MO lakes would be a great place for a Nitro Owners tourney. I know Chargers are made here too and they have an annual tourney. I would be all over that.
