I'm interested in hearing your thoughts on air horns? In the marine section of outdoor stores there are very small cans of compressed air that are air horns. We were at a cottage last summer and they used them to scare bears away when they came near the cottage. All the neighbours had them and when you heard an air horn you knew a bear was close and to get to your cottage/air horn before it ambled your way. Thoughts on using air horns in Quetico? For bear protection only of course.
