He appeared right in front of my mower during my going back and forth. Venemous or not? I don’t recall seeing one like this. Probably 3-4’ long. I let him pass by.
Nonvenomous.
Look at the head, if doesn't narrow noticeably to the neck (triangular head shape), not dangerous. At least in this country. Unless it's a Coral Snake, which is red/yellow/black. But not red/black/yellow.
