Thank You to  – Greg Ellifritz   Many of the questions I receive from students involve the use of chemical sprays.  It seems that nearly everyone carries or is contemplating the carrying of some type of Mace or chemical irritant.  Accurate information about the selection and use of these chemicals exist, but it is often difficult to find truth in the sea of lies and misinformation promulgated by the chemical manufacturers.  This article will provide a simple step-by-step formula for selecting, carrying, and using a chemical spray deterrent.
