Webcam is deceiving you. We've been at club o since Christmas. It's been sunny with Christmas tradewinds, and a couple bursts of rain that last a few minutes.
There are plenty of devoted sun worshippers, like myself, who don't use an umbrella. It's funny, my wife, Peaches uses 100 spf and must have an umbrella--I use 4spf and don't like the umbrella. Anyway, it's a challenge to arrange our lounge chairs sometimes. That explains the lack of open umbrellas.
