A few hundred yards away?
I am sure they can hear it, but damn, it cannot be that loud. It sounds like you guys have some snobby neighborhood to deal with, I hope it all works out.

Again, show up to their neighborhood meetings, and listen in on what they are plotting for their next move. After you listen to a couple meetings, have witnesses there and you ask how you can make it better for them. Yes, you will probably get "just close it down and find somewhere else to run!" But, if you ask the question it will go a long way with the city if you tell them that you guys tried to talk to the neighborhood and find a resolution to the problem. The only problem with this plan, if you do get an answer other than the above, like something reasonable, be prepared to try their suggestions, or it will look bad on the track guys.
