My roommate's g/f works at Mercy hospital in Folsom. She said some huge weightlifter/bouncer type dude came into the emergency room last week with a rattlesnake bite on his foot. She said he was SCREAMING in agony. He's still there and probably won't be released until next week.
Apparently, with today's antivenin, rattlesnake bites aren't that deadly anymore, but the injected venom is supposed to be unbearingly painful. If you live in rattler territory... watch out. They're starting to come out in droves right now.
