Nothing outrageous, but I have been to some weddings that reflected the ethnic history or personal interests of the couple.
A friend got married inside an auto museum. Everything was inside the museum. After the vows, they arrived at the reception line in a Bug Eye Sprite Sports car. After the reception they arrived for dinner in another sports car. After dinner they arrived in another sports car for the cake cutting. And they arrived in another sports car for the dance that followed. I should mention each entrance was accompanied by the loud revving of the engine and horn blowing.
Another wedding was the only Greek Orthodox Wedding I have been to. Lots of crowns, veils and for lack of a better term, dancing of the bridge and groom around each other.
And the most interesting mix was an African American man to a Jewish woman. Their ceremony contained many rituals from West Africa where his ancestors are from, like jumping the broom. And many Jewish rituals were also incorporated including a smashing of a wine glass.
Just a an fyi, jumping the broom is not an African tradition and did not come from Africa.
