Yes and no. I was in Sweetwater for the Rattlesnake Rodeo one year and an Eastern Diamondback (must have been down on vacation) nailed me in the right leg. However, his fangs didn't penetrate the lining of my boots, but rather he got hung up. I grabbed him behind the head, and a cowboy with a machete solved my problem permanently. Of course I let him keep the snake to add to his total.
Have you ever had spur-of-the-moment sex with an overnighter, and although he "played it safe", his protection was a leaker?
