Copperheads are not constrictors. I call BS on that one.
I dunno Brent. I to have handled too many snakes. My experience is even the non-constrictors will be happy to wrap you up if they can. Wrap you up and poop on you,I should say. I think it is defensive behavior common to'em all...Geo
Sure they might wrap around your arm, but there is no way they are capable of restricting blood flow (even constrictors can't do that) nor would, in any way, be difficult to get loose of.
There is probably a grain of truth in that story somewhere, but it's been strongly "embellished". At least that's my opinion. Copperheads seem pretty mild as pit viper go also.
We saw a lot of the doing field work in Kansas.
