Doing a little "Spring Cleaning" of the man cave at the cabin and came across an unfired cannister of bear spray, expiry date 2004.
Now, we have salad dressings in the fridge that old but I figure Bear Spray might be a little bit more time sensitive.
What's the best way to dispose of it, simply take it out back, leave the dogs in the cabin, point it down wind and let 'er rip ? Any concerns about residual crap hanging around in the snow that the dogs or humans might come into contact with over time?
