It's strange that this thread should come forward now. A lady I am mentoring through her first year of beekeeping was stung this afternoon. She went through the class we give here, where we recommend all new beekeepers who haven't been stung recently, ask their doctor about an epi-pen. She lives in the country, so decided it was best to have one. She even took a sting this spring while in town, to see if she were allergic. She didn't react at all. Today she calls and says it's been one hour and she has hives on her torso and her tongue is swelling. I told her to call 911 immediately. They told her to use the epi right then, while she was still on the phone. By the time EMS arrived, the tongue swelling and the hives were subsiding. It's my opinion the epi saved her life. I keep a couple on hand and always will.
Micheal Bush, I guess, has never been in the U.S. Army. If he had, he not only would have seen one, but would have been instructed on how to use it and would have carried it anytime he was "in the field". It is a standard issued item in the field gear.
