I also heard that Wasp spray (20ft) can do more harm then pepper spray? It was said that a woman living alone should keep some by bed and main room and if work in office on desk. Most people do not expect to be sprayed with it. If they get some in eye must go to hospital for care.... Have any of you heard this.. And when I worked at Mental Health the police came to teach self defence, only an afternoon class. Not as intense as yours. Proud of you and your girls as it is very impostant to know. (((hugs)))
