You make an excellent point, one I didn't think of. One of the issues that puzzles me about the condo dwellers is that odds are, NONE of them are going to be much aware of the firehouse UNLESS they are subjected to the siren noise. Condo and apartment dwellers almost never do anything outside their abodes, they don't have yard care, landscaping, snow removal, etc. They cannot wash their cars in the driveways, don't have to maintain the property in any way, etc. I am VERY sure that an arrangement can be made between the authorities and the condo dwellers that the sirens on the equipment will not be used until the trucks are on the main street. So...what is their complaint?
