Yes. So look, you need 3D seismic, right, for almost anything that you do out here that's really meaningful. We're having brand-new seismic run on the Hackberry Creek area. We've got a new seismic and some newly reinterpreted seismic up on Monument Draw -- Hackberry Draw. We clearly have two or three landing zones in most of these areas in the upper section, which I would say encompasses whatever the A and B. There's, for sure, it's a thicker zone over in Ward County. So, that's clearly -- could be free in the upper. We don't -- we're not counting that way right now. There's great C opportunities in both areas. We just haven't got period. Over at Hackberry, the D, I'll call it D, it's a sand. It's a Wolfcamp sand. There's an old development also there. And it looks like it could really be an interesting play, fairly inexpensive, high liquid content gas wells that would be a nice add-on to these horizontal wells in the upper Wolfcamp. And then in the Bone, gosh, we're finding that there's no reason in some areas for us to think the second Bone's any different than the third other than it's specially displaced a little bit from -- in terms of vertical. The Woodford and Barnett over in the Ward area, it's a bona fide good project that we're going to move forward on in some fashion in 2018, primarily reconnaissance because we're running three rigs and keeping the balance sheet in shape and all that, we're a little bit constrained. But we own the right. And when you come to the office, if you do some time, Ron, or anybody else, I'll give you a whole the Bone Springs. I can barely read it. Our fine technology group, whole presentation in the Bone Springs you of both of our areas and also great view of what the potential is out there and it's a resource for sure, and it's widespread, both in the Bone and in the deeper zones. And it's one of those things that a small company running just a few rigs, it's going to take you well to actually do anything meaningful there. But you know how it is, it's great to talk about stuff, but man, until you drill it, you're just flapping your gums, right?
