Annoying neighbors making me crazy! What would you do?

I live in a small, quiet town but there is a bar across the street. Sometimes, the customers can be really rowdy. There would be loud music, a lot of cursing, and even a topless girl on top of a car one night. The bar closes at two in the morning so there are people going in and out all night long. The noise is not so bad but there are times when some men would come in their motorcycles. For some reason, they would make sure that the whole town hears their bikes. This can be very annoying. I have called the police department to report this incident. I have told them that this happens every now and then. The cops have been very helpful. They have given the owner a warning and have been cruising along our street every night to make sure that the customers behave themselves. I would suggest informing the local police department of this suspicious behavior going on next door. I'm certain they would be vigilant in checking in on them since you live near the school area.
