When I was a relative newbie (5 kyu) I was traveling alot and getting exposed to a wide variety of Aikido schools. I would pack my gi and hakama everwhere I went. I made the naive assumption that everyone wore the hakama once they were comfortable with it ( I come from an ASU dojo). I went to a dojo in San Diego and got pretty well thrashed to show me the "error of my ways". Nothing overt and all done in the course of "practice" but it left a very bad taste in my mouth.
