Getting your heart pumping after a snake bite is a really bad idea. I grew up in Arkansas which has the lovely distinction of being home to all four of the poisonous snakes (Rattlesnake, Cottonmouth, Copperhead, and Coral) in North America. Best to stay away from them but if you do get tagged you should stay calm and avoid activity and be transferred to a hospital in a car (ie. don't ride). Call ahead and let them know what's up. My guess is that hospitals stock anti-venoms for indigenous poison snakes. Don't try to suck the poison out. That's a myth. Also don't try to catch the snake. If you get a reasonably good look at it (and if it bites you, you probably will) they'll be able to identify it. Screwing around will likely result in tissue loss.
