One thing interesting that I learned was where the "Hang Loose" came from. I always knew Hawaii was famous for the hanging loose hand gesture, but didn't know what it meant until now. It is actually called the Shawka, because there was once a surfer who had a shark take a bite of his hand, leaving the thumb and pinky finger. Every time he waved to the local people, "hang loose" is all they saw. They called him the "Shawka" because a shark had got to him.
My favorite experience in Hawaii was watching all of the whale breaches. It is whale season and I have never seen so many whale jumping out of the water. One day I was out kayaking with my group, and paddled over to a couple of whales. We were hoping to get a picture of maybe the tail coming out of the water rather than just the blow hole. We were about out of time when all of a sudden the whale started jumping out of the water next to us. It was a momma whale showing its infant how to jump. It was so dang cool! Our tour guide told us that we were lucky. This kinda thing only happens to him once a season. If we were any closer, the whale would have landed on top of us. It was pretty much epic.
The snorkeling was fun to see the turtles and some colorful fish, but there weren't a lot of fish swimming around, so it was hard to spot them. The coral was sweet though.
We went up the Haleakala one morning to catch the sunrise at 10,000 ft. That was pretty cool to be up above all of the clouds.
The road to Hana was a little intense. It is so pretty, but holy cow was it a doozer. I read somewhere that it has over 600 curve turns. Be prepared to get a little car sick, but that part of the island is tropical, so it's worth it.
Having time to travel has been nice. I wish I was able to go with most of my friends who are all jealous, because they're working. But in return, I get jealous of them during the summer when I am super busy working and they all get to go on vacation. Lucky them!
