It's 4 cummins trucks & 1 powerstroke truck that caused this, all younger guys in early to mid 20s, running up and down the main drag blowing smoke intentionally.
From what i was told the one that put it over the top and pushed it to city hall was the kid in the single cab powerstroke with a single smoke stack. He apparently thought it would be funny to smoke out a woman in a convertible car with the top down at a stop light. The soot ruined the interior of her car, the clothes she was wearing and left a layer over her body. She sewed him for property damages. Not sure if it has gone to court yet or not.
Me & a buddy saw a blue lifted quad cab cummins (which is 1 of the 4) do the same thing to a woman trying to get her little kid out of the back seat of a car. My buddy gave him a big a$s chewing the next time he saw him out.
