Great pictures and great cattle. The first is the most impressive, mostly because of your statement about never having eaten a mouth full of grain.
I am 50 years old and I have been AIing cows since I was 14. I had a neighbor tell me I should advertise as an AI technician, he thought there would be quite a bit of interest. The main reason I never have is because of what I can imagine a cow improperly restrained could do to my arm and I know how some people work their cattle. When I saw that pic of you AIing a cow at the end of a lariat rope, it pretty much reinforces my decision. That just ain't worth it.
