I carry a good-sized Knife,but I doubt that it would save Me in an attack by either Bear or Lion.But neither would a Gun.....You'd never see or hear the Lion until your neck snapped,and if a Bear were to charge,you'd probably only get off one round before She mauled you like a Rag doll......
Seriously,in 30+ yrs.of beating brush in critter-friendly places,I've found that watching your surroundings & not Hiking alone is the best defense....
Be Careful Ya'all.....
