The Lark St. area is under siege by hideously loud and dangerous motorcycles/bikes/ATVs, including some mask-wearing drivers. It's inexplicable that APD has stated they don't know how to find them. Anyone who spends even minimal time in this area sees and hears these vehicles any given day up until 4:00 AM. They are in the parking lot of Dunkin Donuts. They are ripping their motors, speeding and doing wheelies on Lark, Madison and in the park. They are racing down sidewalks, menacing cars and pedestrians, and destroying the quality of life. While APD is not pursuing these violators because that could result in injury, innocent citizens are put at risk for injury or worse multiple times a day/night. At least videotape these noise and safety violations, take down license plates, follow them in plane cars and ticket when they are stopped, install free-standing speed bumps, etc. Please address this deadly situation.
