I must confess I'm not familiar with the playa culture. My experiences from childhood are negative. It's either too hot or too cold. Coke quickly becomes warm and flat. I get booored. I'm supposed to be in fresh open air, but there's allways a lot of tobacco smoke which bothers me.
I've noted that the Ayuntamiento has put up signs prohibiting dogs to be walked on the beaches. Very good. Nevertheless, I see many people deliberately letting their dogs run freely on sand. I'm sure the parents are not allways happy to realize what their little children find.
It will be at least a few more years 'til I hire a Hamaca. And I will certainly watch my step.
