hit 'HYBRID'. The streets are indexed, even in Key West...
Official release notes:
Google Maps Hybrid Mode
We've got Maps, we've got Earth, and now we've got a way to view
satellite images with map data. It's the "Hybrid" mode. Very handy for
seeing the lay of the land with, for example, street names on top. Look
in the upper right hand corner of the map image to switch your view
from Map to Satellite to Hybrid (and back again).
