If anyone is reading this this place isn't safe anymore I don't know what's been going on up at the Pleasant Valley Ski Resort but not long after Ethan and Carson left to join them a group of men showed up and attacked our camp.

I can't say where we're headed but we've rigged the place with traps in case those assholes decide to come back.
Reading this note will update the world map with the location of the Pleasant Valley cabins.
