The weather is warming up. Time to get outside and enjoy some fresh air. If you're going to be hiking in the desert, or other areas where rattlesnakes are present, you should be sure you know what to do if someone in your party gets bitten. Rattlesnake bites can be fatal, so it's important that you act quickly to provide medical care.
If you're in an area with adequate phone service, you should call 9-1-1 and arrange for emergency medical care.
