Every week I've been waking up to a chocking smell of buring plastic, rubber, sulfer or chemicals coming from what I assume is the industrial areas. It happens at least once a week, on all different days of the week, but always between 4 and 6 a.m. I'm getting really concerened for our health... we are sleeping with the windows open and inhaling whatever it is that is burning. It is often too hot to close the windows. I'd be shocked if nobody else living around here hasn't noticed it. I want to know if anyone knows where this can be coming from or if someone could check out the industrial area for illegally burning something that can be hazardous to everyone. Has anyone complained or acknowleged this happening before? Help!
