It rained on Monday when people were coming in, and Gate had to stop people until the playa dried. If you drive on the wet playa, the mud sticks to your tires and to your fenders. It eventually jams your wheels completely.
Much of our first week on St. Barth in 2006 was rainy, and this is a photo of the rain clouds as they approach Saba, which is still in a patch of sunlight and blue sky. See the original size photo for better details. This is from our front deck on Ker Roch Glaz.
