I have mixed felings on this one. In my younger days I hunted with a group that cooked over a fire in the morning and evening, we did get into elk off and on so I guess a little fire doesn't hurt. I also think that if you smell like campfire and an elk gets a nose full of that and hasn't smellled if for a while then I think they would be alerted. I think campfire cooking is pretty ineffficent compared to a jet boil or some sort of gas. Cutting, splitting, worrying about the wind and blowing embers, putting it out, all take time and I think time is better spent on just cooking over some sort of gas. There is an old saying " your never alone if you have fire"
