The largest rattlesnake roundup in the world takes place each year in Sweetwater, Texas. Hundreds of rattlesnakes are captured in an effort to control their population. The Rattlesnake Roundup is a fun time for the whole family but you won’t ever see me there as I can’t stand snakes. If you want to get a closeup and personal look at some more rattlesnakes be sure to watch GoPro Rattlesnakes.
