Many years ago my first wedding we had 150 motorcycles in our yard. On humbolt in the heights after 11:00 pm the police showed up and said that we were to loud. They let us continue till 1:00am then they said it was to much that they had to go. That didnt go over well so for the next 4hrs they road around the block. I didnt have any problems with any of my neighbors after that and most of the police were really nice to. But there are city ordinances that some people are not aware of before they start things which brings trouble on them.
I think TNT yours is a typical example of a one time special event that most of us have done and most neighbors are willing to tolerate. But if you proposed to have that same situation week after week and said it was your right to do so and were non-apologetic for it, your neighbors may not have been so quick to get over it.
