The tree farm is private property and so is the fire tower which has a house on it. Only time you can get there are the weekends after thanksgiving till christmas. Both properties are peoples residences and should be treated with respect.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
