I was driving over to my parents house today, heading westbound on I20 just west of Augusta. I had been on the Interstate for about five minutes, when I see up ahead what looked like debris from a tractor-trailer tire blow out, I looked around to see if I could change lanes and avoid hitting the bits of steel belted debris, lots of traffic, no joy. As I got closer to the debris I realized that it was not shreds of dead tire, but about ten black snakes making thier way up the interstate against the flow of traffic, I saw three more groups of snakes in the road, all heading in the same direction spread out over a mile or so, must have been fifty or sixty snakes all together. When I saw the first group of the slithering critters, I was sure what they were, but just to be safe asked my wife what she saw on the road in front of us, and she said snakes.

Have any of you guys ever seen this before? Are there any snake experts here who can explain what I saw? Anybody who doesn't have a clue have a decent SWAG at what the creepy crawlies were up to?

I was driving about 75MPH, so I am not sure what type of snake they were, they were all black, and in this area we have your standard variety of snakes common to the southeast, my guess would be that they were plain old black snakes, but I have no idea what they really were, and I had no intention of stopping and investigating. As far as lenght goes most of them were between a foot and a half and four feet, but there were a couple that I noticed that were 8-10 feet easy.

Sounds like you have delirious Tremors from drinking too much

This was well before dark, that was my first thought, that they wree trying to sun themselves on the asphalt, but it was early afternoon, and it wasn't all that cool today (well into the seventies).
I also considered it may be alcohol induced halucintaion, but I really don't drink, niether does Mrs. Lightning.

ETA: I am pretty used to seeing snakes laying on the road, and any other bit of pavement or asphlat that they can find, especially in the fall, but never in groups like that. I also thought maybe it had to do with them mating, I believe that certain snakes group together when they mate, but I thought they mated in the spring?

These snakes were not grouped like I have seen snakes before, I once saw three copperheads in the woods and they were kind of single file, but these damn things were just all over the road, five or six wide, not in any kind of order at all.

This situation makes me think that maybe there is a good reason for a shotgun with a thirty round drum! I don't care for snakes in general, and have been working in the yard alot lately (mostly clearing an old workshop that fell in years ago, so I have been keeping a 12GA loaded with birdshot handy, but damn, I never expected to need the damn thing and two hundred count boxes of shells on the interstate.

Quoted: So they were heading east huh? My guess is that they were trying to get away from the sun for some reason. Boy are they gonna be pissed come morning! On a more serious note: That is quite odd. I have never seen anything like that. If you witness any other odd animal behaviour I would suggest going the same direction they are because they probably know something you don't. -Nugz

Yep, they were probably what is left of the population of snakes that evacuated Atlanta, even the reptiles can't stomach that ces pool anymore.

Quoted: Just the caulk /foam junk coming out of the  joints in the concrete or something like that. Them snakes been crawling the same place a few days now.  Right before the Grovetown exit?

I guess that explains it, I sure feel stupid. I don't remember if it was before or after the Grovetown exit, but it was in that area. I guess when you are driving at 75, your eyes can play tricks on you.
