Around where I live the worst places to wear a kilt are the bars frequented by the drunken cowboy wannabes. I've had no problems with the biker crowd, millrats or any other group except the fake cowboys. There's just something wrong with those clowns. Of course, an apparent confident attitude keeps most of them in their place and I can look like someone to avoid messing with when I choose. The best solution is avoid places where there is likely to be trouble, and the beer in those places is lousy anyway.
