"Why? Because other people also have a Plan B - and for many that plan is to follow the smell of smoke to a source of supply for various and sundry needed goods."
That's what all the guns and ammo are for. Also, I can also build a smokeless fire to boil water indoors, no problem.
“That’s what all the guns and ammo are for.”
I’ve got them, too...and so do, or will, the zombies. While I will certainly fight if I must, the much better survival tactic is to remain unnoticed and not HAVE to fight. Any time you fight, your risk (and that of your loved ones) of not surviving goes up. A simple and relatively cheap filter will allow you to avoid this problem, at least for a while - so why do you resist it so much?

Please explain that one. I never heard of a smokeless fire before.
