From what I've observed: 13.
Heavy marijuana smokers from the boonies have migrated to my neighborhood for the weekend.
They raised Hell last night when they tried to park their vehicles. It took a dozen gooses to guide the driver who came out of his vehicle with a joint in his mouth.
I needed to run my air purifier full force this entire weekend to reduce the disgusting marijuana fumes, and drown out their constant coughing and rowdy behavior.
I'd like to observe those people in the mainland, where law enforcement takes the most simple drug-possession and noise disturbance very seriously.
