Heading south/east on Bernardo Center Drive, before it becomes Carmel Valley Road, it crosses Dove Canyon where there is a school. The speed limit drops from 45 to 25 in the course of 1 block. I have seen Highway Patrol there several mornings in a row and was in fact stopped (waved down, really) after being lasered going 42 in this zone. However, it was well after school had started and there were No "children present". (I believe this is why I was let off with a warning). Beyond the next light at Winecreek the limit jumps to 50.
