I like the look of a well braided mane, but I honestly can say that I really don’t notice the mane while they are jumping those massive fences (chicken dressage rider here).
There was a short piece on Fibonacci’s groom and the impeccable braids in his mane (which I can’t find now). The geek in me wants to see is mane done in some sort of Fibonacci series braids, although I haven’t figured out how that would work.
