One of my favorite things in Puerto Rico was my private cave tour. If you are in the San Juan area, you should definitely arrange for this tour. You get to visit two caves, and they are very different from each other. The first was a fabulous sea side cave:
The second cave was just the opposite. It was dark, required the use of a flashlight, and had bats practically everywhere. I loved it. At the end of the cave, it opened up to the outside. It was in that spot that I knew it was time to strike a pose. Clay is a professional photographer (in addition to giving fabulous cave tours). With just my phone, he was able to take the picture I have dubbed A Little Tree in a Cave:
Clay also stops for lunch between the first and second cave where you get to have a fabulous meal. Again, Puerto Rico was just an all round fabulous place. Great for locking the knees, and great fir striking a pose.
