I was in the Marine Corps with a Cajun and when we would go out in the boonies at Camp Pendleton he'd always slip away at night. He loved to hunt rattlesnakes and at that time, 64-65, Pendleton was full of them. He'd come back with 2 or 3 shaking the rattles which would cause all of our dark skinned brothers to haul azz.
He'd skin them and cook little fillets over an open fire. Not bad tasting, but a little greasy for my liking.
