Winter hurry up

I'm alive, I'm clear of the rotting city, and I've got leg muscles you wouldn't believe. I'm holed up in a fire tower in the foothills. Eight stories high, no way a zombie can climb it, and I've made trip after trip carrying things up to the top. At night I shiver, but they can't get me.
I found one wandering on the stairs one morning, dressed as a hunter. He'd gotten nearly two stories up before I heard him. I watched for a while, then dropped a rock on his head.
I swear something was moving inside his skull, where the brains should have been. How did he detect me? No way those ruined eyes see anything.
Winter is coming. I'll have to find a cave. Will they freeze solid this winter, crack and crumble? Will they thaw out next spring?
And who's got a hotspot going, somewhere close to me? Why is there still a net?


And how's your day been?
