I'd be careful about using Counter Assault. It's a spray and not a stream. It's best served downwind to a bear. If you spray it into the wind at all and get a lung full it could be really bad. At least it is for me. The personal defense sprays are more a stream than a spray ...most of the time and I personally think bikers are better served by a stream. If a dog was coming at you from in front of you and you sprayed counter assault at the dog you might easily ride into that cloud of nasty orange choking pepper.
