Pete,
That is such a cool picture. That one and the one with the three of us at night are my two favorite float tube pictures of this year. As far as dealing with the trebles, I too stick my pliers in one of my rod holders (that is, if I have room, last time was pretty ridiculous...) so they're always at the ready. For the shorts, I just grab the treble and shake. Most of the time it pops out just fine. If not, you have to grab em on the gill plate or right behind the head (not in their mouth Rob...). I'm feelin pretty good today, I think I'll fish the trailer park tonight and maybe the harbor tomorrow.
