Sure. Let me take the walking systems second, and completely separate from the conversation about new build rigs. So, as respects to new build rigs, Brad, your first comment was absolutely correct. We typically have set our capital budget in December and have our board approve it at that point. We have not, obviously, done that yet, and we won't do that until then. But we have, obviously, these 7 deferred rigs that are carrying forward from our, in effect, 2012 approved budget. So that's, in effect, been approved by our board in there. What we kind of anticipate, but this of course is, at this point, more or less kind of a swag, is that we'll build about 2 rigs per month in the first half of the year. And that's totally consistent with the rate of building in 2012, and so it seems like a very logical expectation for us. Obviously, we have the ability to adjust that number, upwards or downwards, depending on what we see in terms of demand. We're not going to outbuild the market, we're going to be cautious about that. But we're also pretty darn optimistic about our customers interest in these new rigs and the demand for them. So that's kind of a broad oversight, if you will, of the new build. As respects to walking rigs, I have sort of, I guess maybe 2 or 3 comments. The first is that, as you know I'm sure, our original walking rigs are really the industry standard, and we're now seeing some of our competitors really move to try to kind of, in effect, build very similar to rigs that we have been building for a number of years. And where we think we have a very significant competitive advantage, in terms of a certain kind of walking rig. Number two, we've been able to put walking rigs on others of our new AC electric rigs, and adapt them, so that they can have walking systems which allow them to do all the traditional kinds of walking. I see no reason why we couldn't do that for our mechanical rigs as well. But I would say that we're probably the contractor with the greatest ability, and the greatest amount of their fleet already set up for walking, and so we're well positioned in that area already.
