Catholic Wedding Options

This is a Catholic priest to marry someone in a vineyard?
One of my best friends just got engaged, and she wants to get married in a vineyard. She is a practicing Catholic, and even go to church since birth. We talk about the ceremony plans (more fantasies about this point), and she says she really want to get married in a vineyard. She wants to get married by the priest of his parish, but we both have heard that the priest does not marry you out of a church. Is there anything I can do to make it more likely that the priest to get married in a vineyard? If you have the ceremony of the vine is not an option, is it possible for her to have a small wedding, only family in the church, the priest "false" to the ceremony in the vineyards? I told him I was probably less likely to be married in a vineyard (The priest you know who is going to simulate a Sacramento?).
I honestly never heard of a Catholic priest at the scene of a wedding outside a church Catholic.
