OK, I'll play. This guy was sunning himself in my lawn right up by the road a few weeks ago. Ran and got my son (like most boys he loves snakes), but before I could get a good photo he slid into a hole next to my culvert. Take it easy on me guys, non-herper here, but doing my best to educate myself on the non-venomous species. Approx 4.5 - 5 feet total length (accurate I promise). I vote rat snake.
Next, almost ran over (literally) this guy on a walking/mountain bike trail at a local park, turned the corner going pretty fast on my MB and had to hit the brakes to avoid rolling over him. Not sure about this one. Doesn't look like the hognoses I have around my house but I know they can be pretty diverse. Saw a confirmed hognose about a mile away from this snake crossing a paved road. 100% hognose b/c he hooded up at me as a rolled up to check him out and then did that flattening out posture. This snake didn't do either of those things. I know it's not one of the big 4 venomous species. In the photos below, the snake looks lighter colored than it did in person. From a dorsal view (from straight above him) his topside was almost black with little yellow dashed spots all over him. Head was not triangular like a viper. I used a stick to move him off the path and he got a little t'd off, but eventually went on his way. This snake was thicker than the snake above, but not as long (3.5-4 feet approximately).
Thanks fellas!
***ETA - third coast - yeah man I know. I use dropbox and it's giving me fits. The photos are right side up of course on my computer and dropbox folder, but when I insert the link in the TexAgs window and click post they display upside down. Chinese virus on my Mac or something hah. I think I fixed it.
