Hi Doc! Love reading your blog, I found you first through the Lucifer story (reminded me of a friend of mine actually) and then again through your mermaid post and have been hanging around ever since. I looked thru your archive but didn't find this question so hopefully it hasn't been asked before: what is it about horse anatomy that makes their legs so (seemingly) fragile? You'd think being as big as they are, they'd be more all-around solid. Thanks for reading, have a good one!
