Not just in the United States, but also globally. We have this opportunity, being the strength of the brand, our history, it really gives us a chance to do something special, when we open new markets. And just a couple of examples, this last quarter, we did a pop-up in Seattle. We opened one of the finest restaurants in Seattle. We did a pop-up for one day in their parking lot. Nearly 3000 people showed up just for a four hour pop-up. It's extraordinary what can happen for Shake Shack and some of the openings that we've had, if you follow along and you look at what's happened, some of those mentioned in Charlotte, Denver this year, two shacks in Denver, both of them really, really strong starts. It's part of why we invest a lot in the startup costs line that you see so we can capture that opportunity out of the gate. It's also part of how we've, keep the strong AUVs, continuing to go for the company over the long term. And, meanwhile, our business strategy means about 80% of those shacks that we opened will be in existing markets. We love that too, we love going deeper into existing market, it helps our teams, it helps our supply chain and we've barely scratched the surface, you look at us having 102 restaurants in this country. We've barely scratched the surface on those economies of scale. So we really have so much opportunity on the road there. But we love new markets. This coming month, next couple of months, we're going to open in Nashville, Tennessee; Birmingham, Alabama in the fourth quarter and Seattle and the Bay area of Palo Alto. So like that balance, we really think it's a good thing to the brand and for our national expansion. To your question about the learning, as we've noted in previous quarters, our numbers are strong everywhere we've gone. We've shared that information and especially in California, as I noted, we're really excited to continue so much of the strength. So we're excited about the future of where we're headed in development.
