I have a pretty good snake story, although this guy was only a rat snake.
We have a barn behind our house that has been a haven for mice but never for anything else. Behind our house/barn is a small forrest (used to be bigger but all the development has shrunk it down to maybe 50 feet or so by our house).
Anyways, one day I pulled out our lawn mower and gassed it up/primed it. It's one of the ones where you pull the cord quickly to start it up. I pulled the cord and it kept catching, it wouldn't go all the way. I gave it about 4 tries and got nothing, then the end of a snake tail whipped out from underneath and nailed my leg. Needless to say, the snake was wrapped around the inside of our mower. I also hate snakes and so does my dad. We both grabbed shovels and assumed a safe perimeter after my initial shock wore off. The snake eventually came out and it was huge, probably 4.5 feet no joke - biggest rat snake I've ever seen in the woods around my house by far. It was hurt from the mower and it was also ticked, it assumed an attacking position and was striking at us as we wildly swung shovels
It had to be a very humorous scene in retrospect because my dad and I were going no where near that thing and it was probably as scared of us. It eventually made it back into the woods as we chased it with shovels at a distance.
This snake eventually gained legend status in the few houses around us. It showed up one day in my neighbor's wood pile and scared him. My other neighbor saw it another time at the edge of the woods. My dad and I evetually realized where it was living (our barn) when our field mouse problem totally stopped. The worst part was our barn was really small so if you tried to nail the snake in there, it would either go back behind stuff or come at you (neither was worth it for us). It became the ritual for opening the barn: trying to locate where the snake was hiding. Oftentimes it would sit on the top shelf all coiled up and just stare at you as you moved around (scared the heck out of me to go in there). One time I walked in and it was coiled around the shovel on the wall just chilling there.
Our little (actually huge) buddy took up residence for at least a year. During this time, it shed several skins which allowed us to measure it. It was approximately 4 and 3/4 feet.
Last winter, the snake either moved out or died. We haven't seen it since then and there have been no other reported sightings. I still do the snake check everytime I open the door and still turn up the mower at a distance everytime before I start it.
