Yes, thanks for giving us a chance to talk about this. We, at that time -- if you go back to when we considered this it was when we announced it was April, 2016. I think we felt like, we had an amazing economic engine, a great brand. We're really proud of our culture in the way people take care of customers, we felt really positive about the long-term prospects for the industry. But, we did feel like industry conditions were such that we just needed more real estate, and we wanted to have strength beyond Alaska, Seattle and Portland. So that was the idea behind the Virgin merger. It as you guys know, you go through life, you learn stuff. When you do stuff, you learn stuff and it was -- it was a lot of work. But, I think everyone here is feeling optimistic, we're feeling good that we're getting through it, and I think we really feel that we have materially enhanced sort of the cash producing sort of capability of this economic engine. We've enhanced career of security for our people in doing that. As you mentioned, I'm extraordinarily proud that we borrowed $2 billion to do it. You guys know, our people did it with no investment banks with no, nothing like that, they just went to the banks and borrowed $2 billion on their own and we're going to pay three quarters of it off, in three months' time, so we're really proud of the team. As we look at doing more, you know I just think, my own view of the world is it's a combination of organic growth and M&A. We've done amazing with organic growth. I'll just tell you -- and different people around this table may feel differently. But, as I look at the next few years, I sort of see the biggest opportunity us growing organically, pushing -- taking what we are proud of what we feel like we do well, and pushing it organically into markets where we're already strong.
