While I don't carry when tripping, the influx of strangers to the backcountry has me reconsidering. Granted, the long drive is the most dangerous part of any trip, but I've run into my share of miscreants over the years, and had a couple close calls. 2 lbs of protection is worth many lbs of cure, right? If nothing else, it would be a fine noise maker for bear repellent. I usually ascribe to the 3 portage rule - drunks and trouble makers are lazy I figure. Age may subvert my theory eventually (according to my knees) and make us more vulnerable.
