Here in Texas (elsewhere as well), there is a group of bikers,
Patriot Guard Bikers, that attends a lot of the funerals and are kind of, well I wouldn't call them a "barrier", but I notice the nutty little Baptists from Kansas aren't making it a point to try to interfer with the funerals the bikers attend (at least the three I've been to), and we'll leave it at that. There's been several threads about the Patriot Guard Bikers on FR, and I believe several FReepers are members.
