Well, I realize I'm an ole fossil with old ways:), but IMO, marriage is something serious, very serious. Somehow for me doing it on horseback somehow distracts from the seriousness of the event. It's a joyous event, but not an appropriate event to add animals into it. They are making a statement enough doing at a CTR. Let it go there. JMO, tho:)

I'm not overly traditional or formal certainly, and I agree. The type of ceremony can reflect the style of the parties involved without the trappings becoming more noticeable than the vows. I could say the same thing about extravagant expenditures, they can be as distracting to the point as horses can.
