Yes. Let me tack onto that a little bit. I think -- if you look on Slide 48, it's on our website, and what it shows is the historical cumulative oil production per well from the Mississippian. This is looking at all the historical vertical wells, and there's a lot of them. And by far and away, the best vertical wells in the play are on the northern part of the Nemaha Uplift in Kay County, Cowley and Sumner up into Kansas, right through that little area. The vertical wells in Kay County are the highest. They're at 85,000 barrels per well. If you think about a horizontal well, really, it's a multiplier of a vertical. So a horizontal could be, in any play, really 3x a vertical, 4x, 5x, 6x or whatever. So one good indication of where the best horizontal wells are going to be is look where the best vertical wells are. So -- and to compare that, if you go way off to the western side of that map, or that stratigraphic trap shown in green, as Ray mentioned, the vertical wells, say, in Woods, Barber, Comanche counties are 13,000 barrels, 22,000 versus 85,000. So they're significantly different. And then there's a slide right next to it, on 49, that shows -- as you go far west, the other thing that happens is the play gets gassier. So we are, there's better vertical wells, higher oil cuts. Then the question is why, and it's back to those things that Ray said. We think when you're up on the Uplift, or the things you mentioned, Rod, early on, when you're on the Uplift, you're -- one, you're higher structurally, which we think is a positive; two, you have a chat component that when you're on the uplift that you have, but when you're off it, you tend to lose. In fact, it's not just being on the uplift, you've got to be on the northern part of the uplift to have that chat component, plus, you have a higher degree of fracturing up on the uplift which enhances permeability. So we think that's what supports better vertical wells, so far, or better horizontal wells. And then like Ray said, we'll just update you with time as they are just like we did in the Marcellus.
