Sounds like every time I go up to my cabin. Luckily we have not had any vandalism up there, but we are certainly vulnerable to it. Also fear animal invasions, mostly the porcupines which will eat through almost anything except the cement board + metal, but I have also heard of bear break ins now and then. They can tear through a cabin wall fast if they want to. We did have a cooler attacked by a bear one night, luckily it was out side. He just bit it and flung it into the air like it was nothing. Luckily, it was a fairly young one, and we were able to chase him off.
My friend said if he had a video of me running after and chaining it wearing nothing but my boots and my underwear, with a flashlight in one hand and my Glock in the other hand, he could have made a fortune on youtube! We had "shooed" him away multiple times that night, but after I ran after him and chased him into the woods, he did not return. We were staying in the cabin while building it, and did not have the front door installed yet.
