I know this might be an odd question, but...
We will be spending about a week and a half touring around the area in August, starting and ending in Jasper. I think I'd like to have a can of bear spray with us, just as insurance, but since we are flying home we won't be able to bring it home with us. I see renting is an option, but by the time I pay to rent it appears it would be cheaper to buy it. Is there anywhere that sells used but unexpired bear spray? There must be an abundance of canisters somewhere, from people like us who want to buy it but can't take it home with them.
