You can get anti venom in la manz. If you hike a lot it a good thing to carry. I have been hit too many times. Half the time I don't believe I was injected with venom as I had no symptoms. The small ones seem to have done the most damage, my thinking is that they haven't learned the correct dosage yet. Best advice is to stay calm and think of a way to slow the venom from hitting your heart all at once. If your lungs start to feel cool I would do double the dose and head for the hospital.
