 Grand Canyon is definitely something I think would be on a list of things to see for sure. But going back to if you wanted to tackle all seven continents and you wanted to make it to Antarctica, Jennifer came back with, yes, you can go and visit with National Geographic and visit the Penguin Study Site, which now is on my list of things to do before I die. I didn't know it needed to be, but she said there's very limited seating and there's a waiting list and it's expensive, which I'm sure that it would be.
