I really like evening fires, both for warmth and ambience. Of course, I live up north and except for mid-summer, the warmth is always a plus.
I strongly dislike the smell of burning plastic and don't come on the river to smell like it.
I also don't really like smelling like campfire, but tolerate it. I prefer dry wood fires and love my pop-up pit for minimal-smoke fires. I'd rather have no fire than a wet/green wood smoky fire.
I also dislike morning fires as they take too long to cool, and distract from breakfast/packing/launching.
Learned the trick of stuffing everything into plastic bottles that seem to find their way on the trip, with a stick or similar. You'd truly be surprised at what you can stuff in them, stick the lid on and no smell, compacted as far as it'll go, toss in the trash at the end of the trip.
Since most of my meals are pre prepared and vac sealed, there's not a lot of waste past the vac seal bags to get rid of.
I'm tempted to try the "garbage ball" method others have tried using pallet wrap. I also like the plastic bottle recommendation...though I don't drink much in plastic bottles I'll have to try a few. Would like to have something to odor-seal my vac seal bags since I mostly camp in bear country.
I also just bought a battery-powered electric bear fence. That BIG bruin in camp 2 years ago was a warning.
