Every since this motor cycle club moved into our neighborhood, we've been having issues w/them racing through our street late @ night. Have tried to report to police but by the time they arrive the bikers have stopped, then maybe 1 hr or so, they are back. I've called our precient but they tell me to call 911, I've sent many inquiries to their website. they tell me to call 911 also It's hard getting sleep. I''ve fallen asleep many times @ work because I'm not sleeping @ home due to these bikers. I need help before I loose my job or develope health issues because of lack of sleep. This has been going on over a year. It gets worse when the weather is warm. Can you please help or direct me where I can go?. i am so tired. Thanks
