One time in the ER i treated 6 cops and the perp with a bad pepper spray wind situation. It was bad. A few cops had bad pulmonary reactions to it. The perp was high on meth and was mildly annoyed. You would be high to fire that off in a tent. When it comes to protection i use guns that work, not have nice lines. I have srh both regular and alaskans with night sights and swift aframes or copper solids. This i have confidence in and have no questions of power and efficacy. More and more evidence coming out that bear spray recommendations are due to biologists not wanting dead bears and anecdotal evidence bc most people cant shoot let alone shoot in a stressful situation. Practice practice practice and ise reliable good bullets of an ample caliber and a handgun becomes your best friend in that tent.
