I have been hunting in Colorado for the past 13 years on self-guided hunts. I have all the equipment for the hunt, including tents, cots, use of ATVs, stoves, and down to the silverware. For the past 3 years I have invited a co-worker and he has brought along atleast 2 of his friends each year to come with. I have also invited an older gentleman I met at a RMEF banquet, totaling my party to 5. For the last 3 years these hunters have brought only their clothes and guns. This last hunt I supplied 3 of them with cots, sleeping bags, and other necessities. One of them drove their crew-cab pick up, and all they carried was their clothes and guns. I drove my vehicle with a trailer carrying all the equipment from tent, heating stove, cooking stove, shelter, lanterns, cots, and chairs. For the expenses of the trip this year, for food and fuel, was $1,200 from MN to CO. The gentleman from the RMEF banquet thought it would be fair to split the cost between my four hunting companions, since i invited them and supplied all the equipment. The other 3 thought the cost should be split 5 ways, including myself. How would you share expenses on a trip like this?
