I always thought that cows were ok. I understand that I can't take pictures of bridges, railroad stations, government buildings, area 51, children of others, my own children in the bath, ...... but cows? I have some of my best pictures with cows in them - well maybe only one or two. Swiss cows are the best but I live in Florida, so it's a little bit of a trip to go to Europe every time I want to photograph the countryside. But, if that's what I have to do to avoid jail, I'll just have to ... sigh ...
(For those who don't know about area 51 .. Google it ... especially "conspiracy theories"}
