I got stung almost 300 times on my left leg alone when I accidentally stepped into a yellow jacket nest in a bank of the Brazos River (my leg sank to about mid-thigh). I was teenager, maybe 14 years old at the time.
My dad used an entire carton of smokes to draw the poison out of the stings while he rushed me to the hospital to get 5, yes 5, antihistimine shots. My legs were swollen for a week (the right leg took many hits, too).
That is my worst injury to date and I am now allergic to yellow jackets. Bee stings suck.
