One thing I wish I got the chance to do more of was snorkeling while we were in Rarotonga.  The lagoon tour that we did was really quite amazing.  The water was light blue and unbelievably clear; it is the kind of water I never thought I would see in person let alone snorkel in.  The creatures in the water were another amazing site to see. I feel like I saw more fish during this snorkeling session than I have in my whole twenty-three years leading up to this trip.  In addition, I saw a small eel that traveled from one rock to another, as well as Roger (a giant moray eel).  I could not believe how huge Roger looked when a crew member from the lagoon tour pulled the eel out and up from his hiding spot in the rocks!  Another thing I recall seeing was the coral garden in the lagoon.  This is where a metal grate/structure is placed on the sea floor and pieces of coral are attached to the top and grow with less space restrictions than on the coral reef itself.  It was really cool to be able to see a protective environmental measure that I have learned about in school while I was out in the lagoon; I was glad to see that the locals put forth those efforts and were educating other people and tourists about what they are doing to enhance their coral reefs.
