Depends on the snake.
The reality is, you should have a cell phone on you, and hopefully you'll have a signal. Where you are, Nanci, my biggest concern would be Eastern Diamondbacks, which can inflict a deadly bite with ease. If one of them gets you 60 minutes from help...you might want to pray...
The best course of action for any viper bite, IMO, is to remain as calm as possible, and walk as quickly and calmly as possible to the nearest available help. The entire time you are walking, you *should* be trying to contact someone via cell phone...preferably 911 or a nearby forest service ranger station.
*Most* viper bites in North America aren't going to prove fatal, unless you have an annaphylactic reaction. But ALL need treatment. So be calm, but get help. You're not going to die within a few minutes. In fact, you probably have a few hours before any serious systemic reactions set in, unless you are allergic or annaphylactic.
Keep that in mind, and try to stay calm. In perfect world, your cell phone woprks, and you're not alone. I know that doesn't always happen but...we can at least try...
