What's happening?

When Tommy and I arrived to "La Laguna" (laguna = lagoon) yesterday, we noticed that something was different...


... all these guys on the shore, only one in the water, we were puzzled about it.
What was happening?


After a while we saw the sign: "PELIGRO, PROHIBIDO NADAR" (Danger, swimming prohibited)...


... and "PROHIBIDO ENTRAR A LA LAGUNA" (Entering the lagoon is prohibited)


That was it!! These smart guys were just following the law ;)
