30 years ago, I think the view was you needed about 0.5 million people to trade area plus certain number of businesses and all that kind of stuff. Today, that number could be as low as 200,000 sometimes. It depends. Some of the smaller or medium markets we've gone into in the last few years generally are markets where our competition -- our direct competitors were, in many cases, for 20 or 30 years and we had just never gone there. We've gotten probably a little more confident that when we go in it, there's room for both of us, and we've done relatively well. I think the other thing is, if you look back over the last few years and my guess is in the upcoming years, there'll be some infill opportunities. I've used the example on calls on the East side of Seattle, in the Bellevue side of Seattle where, historically, we had three locations, Issaquah, Kirkland and Woodinville. About two years ago, we opened in Redmond. And we only added -- let's say in those three locations, had about 190,000-ish members between them, households, so 60,000, 65,000 each. We only added about 10,000 new members in the next year, but you had a lot of loyal members that started shopping more frequently because we were closer to them. Part of that comes with you have high volume. And those -- that example, I think as -- before we opened that fourth location on this side of Seattle, we had I think over $800 million aggregate sales, 1 in the low threes and the other two in the mid to high twos. And when you get to that level, that gives a little more comfort that you can afford a little cannibalization. In that example, I think the first year, net of cannibalization, we did $120-plus million of business, $120 million, $130 million of business. So, it's pretty easy to estimate and guesstimate what you think you can do particularly when you have a loyal membership base. And then there are other markets like if you look at the Greater Los Angeles market, I'm talking greater geographic market, I think we probably have 60-ish -- roughly 60 units. The view is we can have another 15, but they're all very specific geographies, which are not quite impossible, but very difficult. And we'd be thrilled to get 1 of those 15 open every couple of years, but you don't know if that can happen. So, I think it's all over the board in terms of smaller trade areas, markets where our competition has been and we are just entering and then continue the expansion and infills.
