While online one of the many times I shouldn't be while at work, I ran into a slide show of an Antarctica cruise. It was breathtaking. The beauty of the icebergs. The vast untouched wilderness. The opportunity to be feet away from a society of penguins! I guess you could say it's #1 on my bucket list. I say bucket list because IT IS EXPENSIVE! The cheapest cruise we found(which is really the only way you can go if you want to spend a lot of time on the continent) was over 4k a person!
But, oh, it would be so worth it.
