i wouldnt worry about calling the police thats what they are there for. ive had to do it before and id do it again. i dont need to hear their music if i wanted to hear music id put on my own music and listen to what i wanted to hear not them. our neighbors here in town do this and hubby cant stand it. they are always outside and blaring their music they listen to country hubby hates country so he is always taking his cd player out and blaring his music and they dont much like that. hes into the techno and nine inch nails ozzy stuff.
