I live in a heavy biker area. How do I navigate people from biker groups potentially attending the same wedding?

I live in a relatively poor rural area known for being a stronghold for a specific biker gang. A lot of my friends come from biker families, and even if they aren't direct members, they still have an allegiance to the group. Upon researching my wife's list, some of the spouses/boyfriends belong to a different group that isn't known for having the best relations with the local group. What's the best way to navigate this?
