Is this a new "circuit"? I've never heard of it before. Once you get stuff together, I'd definitely be down for a few tourneys. Well, Margarita is definitely a good spot to float tube. Don't know about the facilities and all that, maybe Rob will jump in here. Then there's Lopez, I've never tubed it, and haven't fished it much, but it's also a good lake. What you might want to do is check out some organizations like wonbass and see what they're schedules are like, then look at some of those lakes and find out about the facilities and whether or not float tubes are allowed. Let's hear some more info on this deal, I'm definitely interested.
