Woven bird nests hanging on palms near the marina.
These hanging nests were always attached to the very end of the palm fronds, making them look like Christmas ornaments of straw in the tropics.
The treasures I had to leave behind on the boat. The huge sand dollar (the size of my hand) and sea biscuit were too fragile; the red jasper and piece of Panama rock were just heavy bits that didn't make the weight cut for our luggage.
These cargo ships are the normal vessels plying these waters and are on the move 24x7, so we must always be watching for their movements.
