Most recently would have been in Playa last November. On the giant sand bags in front of Playacar. They are great fun to play around on. (one) in particular, is slicker than snot. I however did not notice this as I walked onto it, drinks in hand. I started to slide... And remained upright but stranded right in the middle. By now everyone on the beach, and my wife and daughter sitting on another sand whale were watching. I took (one small step) and in the next instant my feet were above my head in the air. I came down flat on my back and smacked my head. I could hear the collective crowd on the beach behind gasp!
Nothing funnier than watching someone get a concuncusion!
I LUCKILY did not have one but I stayed WAY away from the sand whales the rest of the day.
