When I set out to take James up on his postcard suggestion to dive with great white sharks, I was certain it was an activity for hardcore adrenaline junkies. Heart racing, chest pounding and the world's scariest shark a mere few feet away; it was certain to be intense and amazing.
What surprised me was that following the initial excitement of seeing the sharks up close, my mood turned quite quickly to being calm and peaceful. I know you're probably thinking that "peaceful" is the last word you'd use to describe a great white shark encounter, but for me it was true. They're elegant and powerful animals that deserve our respect. Being surrounded by them in a controlled environment is exciting but also tranquil.
The 30 Postcards Project video of the experience will give you a sense of what I'm talking about -- and hopefully will encourage you to put cage diving on your bucket list if it's not already there.
