Bluefin.. I would also be interested in filling in spots on split trips. I've wanted to do one for a long time now but my friends are stingy. So I'm willing to fill in on split trips.
Let me know. And I'm still interested on your open seats. I work as a cook so I have no problem making macaroni salad. Just tell me what you want in it. Tuna, seafood, I make a good mac salad. I make them all the time at my job. My best one is with veggies, Italian dressing, and a variety of meats.
I'm gettin hungry now!!
