I'm in SC and have seen a number of "brown snakes". They say they are good around gardens for insects and worms but will still put a little hop in your step when it goes skirting by your boot while weed eating! Did a yard this morning(before the rain out) and saw 5 within a 300 sq ft area. Must have been a nest? I've only seen one poisonous one this year and it was a copperhead. Don't know how the mower missed him but I screamed like a little schoolgirl when that thing came rolling out from underneath and between my feet!!! No, I didn't get him with the mower...Like I said, I was to busy screaming like a little school girl. And try to live that one down when your the owner and your crew is rolling in the ground laughing at you.
