If you’re going down Murray Lane and Brentwood High and Middle are on your right, then you turn right onto Granny White Pike, I’ve noticed a cop who sits in the neighborhood on the left as soon as you exit the school zone. My friend was beginning to speed up from 20 (she was at 22 i think) and got pulled over. Be careful of this in the mornings! I’d stay around twenty till you’re far past the neighborhood and a little bit past Granny White Park. If you do have to go Murray Lane to Granny White, you can also cut through McGavock . But you can’t go above 34-35 in there otherwise you Will get pulled over.
