TCRanch.. I've recycled a few... If I can't remember the animal that had the name, I'll recycle it!
I have a few that had related names... If Tizia had more heifers than just Mega, I'd have continued with Giga, Tera, etc along that line.. Instead Mega's daughters have taken those names.. the other theme for Megas calves have been Sofa, Divan, and I'm waiting for Chester(field)
I've used the names of great people in specific fields (Philosophers, etc), Rivers and lakes, volcanoes (Hekla, Lava, Helena and a bunch more)
Then I decided to have some fun.. and in all my FB cow pictures I tagged my friends!
