I honestly do not remember if I carried at my wedding. I probably did, though since I never go naked.
Being that nowadays I'm the guy standing in the middle of the wedding party telling the bride and groom what to say to each other, well.... I've carried in a few weddings (concealed).
Someone questioned the need for weapons at a wedding. I would venture to say that one is no more nor any less safe at a wedding than at most other events. So, why not carry? It just makes sense. Regardless of how crazy the future in-laws are, a large group of unarmed people is simply an easy target.
All of that aside, one of my professors in Seminary shared a story- in McCurtain County, OK, a preacher was conducting a funeral for a man whose family was feuding against one another. The preacher walked to the pulpit, pulled a large revolver from under his jacket, laid it on the pulpit, preached the funeral, re-holstered his weapon, and walked out. It was a very peaceful ceremony.
Being that much of my family came from McCurtain County, I can see where his story was realistic.
