What are you looking at?

In a city surrounded by so much ocean, of course we have lifeguards.
Along the open ocean side of the city there are periodic life guard
towers the rather resemble the wooden log playground equipment being
built around the city in the plazas (João Enrique really likes to
build pracinhas). They are big enough to accommodate a couple of guys
but not nearly so that they can stay out of the sun except in the
middle of the day. The rest of the time they need to provide an
additional manner to get out of the intense UV. These two have hung a
banner along one side of the tower; the side that faces the ocean.
Luckily there does not seem to be anyone in the water at the moment,
so they are not missing anything. Stay sharp guys!
