Evenings between maybe 7 and 11, motorcycles are fairly consistently exceeding bearable volumes, either racing or just plain speeding. Whatever they're doing, they're making sure to be as loud as possible. It's unbelievable how loud they are. This city has a noise ordinance at http://ecode360.com/12360650.
§204-4, C, (1) talks about motor noises and seems to be inclusive of this problem.
This has been an issue for at least the two yeas I've lived here, and it completely shatters the peace at my home. I can accept Tuesday night Motorcycle Night in Lowell. I know that's a tradition and I can appreciate it. But this is every night.
Is there anything that can be done? Can you set up cameras or police?
