Braiding Mane for a Show

Do you braid your horse's mane before a show? I've heard controversy over the topic. I have never braided my horse's mane for shows, but some of my fellow riders do constantly.

Depends on the show. For eventing, Pony Club rallies, and 4-H shows I don't bother, but I always braid the mane for hunter shows. I keep my gelding's tail pulled so it looks neat without having to expend the effort to braid it.
