Run Away Bay

I took off for Vieques on a whim and a hot sauce hunt, got lucky on both (the ferries actually GOT me to Vieques & I came home with more Coqui Fire from Jimmy). I've got a lot of photos I want to put up here but time being short at the moment, and the fact that last night was a big Puerto Rico Constitution Day celebration in the plaza with great music and friends, I'm on slo-mo. So for this morning's photo, you get what might be one of the better visual jokes on Culebra at present.I'll get a better day time shot later but I can't wait a second longer to share this.

Who decided where to put up the tsunami warning sign? And what does it mean?
(and what a romantic spot to have a chat)
