Wait a Minute..What Happened?

Dear Wal,

Today I cam home to this:

Thankfully, Dad didn't hit anything when the truck started sliding. Dad came and got me at school, which is odd, because as you know I ride the bus to the library. So I ask him what's going on, and he tells me that the truck is stuck, because it slid off the hill. I didn't realize he meant this hill. 

I mean, how did he manage to do this? I have no idea. I don't think he does either.
Now we get to wait until the ground either dries out, or freezes. Oh joy.
