Pretty sure that was a nerodia. Hope you didn't kill it.... they would hurt anyone unless you grabbed him directly (trust me, I've tried

, dozens of needly perch grabbin' teeth)
Not much need to keep your guard up until it reaches 70's. Snakes of the genus
Nerodia generally come out on warm winter days to sun while
Agkistrodon (Copperheads and Cottonmouths) usually don't come out until it reaches highs of low 70's. Harmless and crucial part of the food chain, but when molested they will act like they are the devil himself and stink to high heaven. They just don't wanna get hurt by us fishermen
Do you think it would be of benefit to do like a seminar at some metroplex lakes or an online video thing on snakes to keep our fellow TFF'ers safe? Might be kind of fun to work on once spring time comes around.
