"I would assume "MACE" is much more potent and volatile since it is restricted here. I'm not in favor of key chain sprays, unless they have some kind of REALLY good cap or safety."
I can chyme in the voice of experience here. I have a keychain bottle on my Camelback for my running days. I noticed that the safety was completely off from simply being shaken about. I have two small boys at home. Fortunately, it was far out of reach for them. Still, I think I will open carry on my run days instead. The only thing is that this stuff is great for feral dogs or dogs whom belong to careless owners and are a bit overly aggressive. Windy days are NOT a good day to use mace!
The natural state of man, the way G‑d created us, is to be happy.
