 And that was in 2018, actually. It was in January 2018. I'll never forget that. I was leading a group of about 12 people. We were on our first, what I called then, Stone Circle Research Expedition. And I had 12 people here from all over the world. There was a group of Americans here as well. I think six of the people were from the USA. And we were going up the mountain, making observations, doing research and so forth.
