TITLE: How should I handle this hit and run?
POST: While trying to drive home last night, my car got stuck in a steep curve covered in ice. I couldn't turn around to park at the bottom of the hill, so I backed as far out of the curve as possible and left it there for the night. The car was completely off the road.

When I walked down to move it this morning, I noticed it had been hit, denting the fender pretty badly. It had obviously been hit by someone coming down the hill. My boyfriend found a note stuck in a window that said "DUDE SERIOUSLY? Move your car IDIOT." I'm not a prideful person, I realize that I was not parked in the best spot, but if I could have moved my car, I would have.

Is it petty to try to find this person and get my car fixed through insurance? My car is already pretty beat up, and I was prepared to just let it go, but I'm feeling pretty pissed about the note. I understand their car probably slipped on ice and they got freaked out/pissed off. I'm sure they didn't hit my car on purpose. But I never would have left someone a shitty note, I would have left my name and number. I live in a small neighborhood, so I am positive I can find out who they are. But before I go to the trouble of filing a claim, I want some objective opinions on whose fault it really is.
Thanks!
TL;DR: 
My parked car got hit by another (moving) car on an icy hill. Is it my fault or should I find them and pursue an insurance claim?
