On Nogalitos heading north, there is a really short school zone that extends for only a block or block-and-a-half, and is marked only by a single, unobtrusive street sign (i.e. not lights that flash during certain hours). Literally right before the speed limit goes back up to 30, there is a driveway partially hidden by some fencing where a cop on a motorcycle will wait to pull over drivers. Since the school zone is so small and the signage is so unobtrusive, most drivers heading north don’t even realize they’re speeding when they’re going 30.
