As a side note...
I live out in the Texas panhandle, a world away from most of you guys. My brother in law is a rancher (a real cowboy, on horseback every day). Several years ago he went to rounding up rattlesnakes on his ranch as certain areas were infested with them and when they bite cattle, it makes the cow very sick and can even kill them.
The times to "hunt" for rattlers are in the spring and fall, when they are near their dens. There have been seasons when he has caught HUNDREDS of the critters from a single area!
He sells them to some folks in Oklahoma by the pound, ALIVE.
Come visit West Texas some time!
