I was carrying a large bucket of water and half a bucket of feed to the barn for the sheeps. I didn't realize the ground in front of the barn door was solid ice, so I wasn't wearing my YakTrax (crampons). I went down hard. I banged my knee on the hard ice; it hurts like hell but fortunately I don't think I broke anything. The bucket of water spilled all over me and almost immediately froze. I was literally frozen to the ground and had to fight my way free, not an easy thing to do when you're on solid ice and have no traction. My roommates were so engrossed in their computers they never heard my cry for help. If I'd broken something or been unable to get up, I'd have frozen to death. Thanks guys.
The sheep got their food, but water bucket was empty, so I guess I'm going to have to venture out there again. I don't know how, all my cold weather gear is soaking wet. I used a piece of a broken stall door to make a bridge across the ice on my way out of the barn, so hopefully I won't fall next time. I'll be sure to wear my YakTrax too.
