Talked to my venue today and while discussing my choice of caterer, I found out that my venue does not allow pot luck weddings or some homemade wedding cakes. Turns out the state it's in does not allow food to be brought in that was prepared by people who aren't licensed to prepare meals. It's the whole: food poisoning can ruin a wedding thing. .
So yeah, for anyone out there considering a pot luck wedding, if you needed any additional reasons as to why it would be a terrible idea, here's another: your venue may not allow it.
