On the TwentyMile Trail Hike on September 9, 2009, your webmaster, Lou Miller, was stung twice by bees as were several other hikers. I am allergic to bee stings. Normally, I carry an EpiPen with me but could not locate it before the hike. (I did find it the day after.) If you are allergic to bee stings you can suffer an anaphylactic reaction which means your blood pressure drops severely and you have difficulty breathing among other symptoms. It can kill you, if left untreated. The anaphylactic reaction can occur a few minutes after the sting or several hours after the sting or not at all.
