I totally agree with this statement. I only know of two people off the top of my head that have been bitten by a venomous snake. My Grandpa by a copperhead and a friend of a frind by a cottenmouth when playing Steve Irwin (not a good idea).
Grandpa's bite was treated like a cut, but no antivenom or anything like that. My understanding it is like a wasp sting, if you are allergic your in trouble, but otherwise it stings and goes away. The cottenmouth bite caused some severe skin and muscle damage, but the guy lived. Hopefully will not pick up another!
As a former employee of the State, when involved in a 48 stream sampling event across the State one summer, we saw one cottenmouth at a distance. Over the years of fishing and stomping around in the woods, I've never seen a rattler and only a handfull of copperheads, many non-venemous species however. If you see a venemous one, leave it alone and you should be fine in my opinion!
