I'm going to be shooting a scene in a local small town in a few weeks, and the scene is going to be on the sidewalk in front of the pizza place. I'm planning to shoot this in a guerilla-style (4 actors, me, camera operator, assistant), and I was wondering who I need to contact to shoot here without getting in trouble? If its in front of the pizza place, do I contact the owner, or do I need to contact the town officials? I'm not going to be taking up the whole sidewalk, by the way.
