I've only seen one dead one recently and it's on the way to my barn. I did see one a couple months ago dead on the inside shoulder on the interstate. I had to commend that deer for having the determination to try to cross 7 lanes of traffic and jump 3 barriers.
I haven't hit a deer, but I was hit by one in 2009. Deer season happened to open the next day too.. I was driving in the middle of town and it ran out from behind a tree into my passenger door, got up and ran into the park across the street. It was a younger buck. 3 cops were sent after it to kill it so it wouldn't hit/get hit by another vehicle. They never found it. Not impressed that it didn't die.
I happened to be in an auto body class in high school at the time and found replacement parts, painted them, and put them on myself for $250. Not bad. http://i2.photobucket.com/albums/y50...1106091247.jpg
(That crater at the end of the fender was caused by me sliding into a truck that April, but everything on the door all the way over to the top of the tire was the buck). Got a lot of comments on my lack of a side mirror because I never replaced it (wasn't legally required to and the guy I got the door and fender from wanted a ton for the mirror because it was electric, but my car didn't have the hookups for it).
