Tournaments, I split everything in half. I start out with a full truck and boat of gas and when I get home, I want to have a full boat and truck and we split everything we used. I feel that's pretty fair. Entry's split half,winnings half, etc.

Now, if for fun and it's somewhere close---I wouldn't worry about it. Buyt, if I am going somewhere far, like Cumberland or KY Lake, I feel if anybody goes, they should chip in some money. But, everybody I fish with has a boat and they know the expenses and they usually pay up without asking---I feel that's just the way it is. At least I know I would offer money. Fishing isn't cheap anymore---at least not going to the "good" lakes. Their pretty expensive for me.
Didn't seem to be so bad years ago, but these gas prices sure make everybody watch what they do---it really stinks too. I sure have passed up fishing many times because of money.
