Having a backyard wedding. Between 100-150 people. I'm not sure if I need a permit or not, but I'm afraid to ask because if they say yes and don't give it to me I'm screwed. Thoughts?? All the neighbors are cool with the wedding being there (and most are going) and I've set up a shuttle service so there should not be numerous cars in the neighborhood. There are no tents because they do require a permit (and are super expensive). Help :-/
