Between Scott Rd. and 128th street, there a are a couple of groups of old guys in reflective vests that have radar guns and "your speed" signs. Don't think you're safe though, coz right before you hit 128th, there's some real cops with radar guns who seemed genuinely disappointed when they saw that i wasn't speeding. (although i was doing about 90 before i came to a screeching halt at a yellow light and saw them in the distance as i stopped.
Just thought i'd throw that out there.
