Solo Winter Camping With Only A Tarp

I went winter camping in northern Minnesota without a tent. I brought 2 tarps and a sled to carry all my gear. I found a rotten oak tree and chopped it down but it didn't fall right. I switched camping spots. My firewood was wet so I had to rely on my Mr. Buddy heater. I cooked a wonderful wagyu steak and had coyotes or wolves come near my camp.
