Loaded a group of yearlings this morning to go to stock yard. Reached around the side of the trailer to latch the trailer gate and it felt like I was shot in the arm with a large caliber rifle. When I got myself together I took them to the yard and unloaded and drove back home an hour each way. I took a shower and headed to the Dr. He took one look and said ruptured Bicep. He set me up with a surgeon.
