I’d probably respond in general as opposed to give you any real detailed specifics, but we’ve been pointing out for a while that the entire infrastructure is pretty taut, and it doesn’t take much in the way of an interruption in any one point to cause something to significantly move out. As Harry mentioned, WTI and WTS differentials used to average about 450. Now, they have kind of gotten to flat, if not flipped around, where WTS is more valuable from time and time than WTI. And then, you got the differentials on just a geographic basis between Midland and Cushing, WTI barrel, same quality barrel, and yet what used to be a $0.70 differential goes out now to $7 or $8. And again, part of that’s infrastructure related, part of it’s quality related, and some of it gets combined, so as Harry mentioned, we used to – the industry used to blend quite a bit of WTS with the lighter ends of the WTI to provide what the refiners used to want and value most, and now they value the heavier sour barrel more, because they're being inundated with light sweet barrels, and so when you un-blend so to speak, the WTS barrel to segregate it, you actually create more light sweet barrels in the whole process than the market used to have. So, I think you have got your finger on it. I think what we’ve seen so far already with the movements -- just here the other day, we were looking at light sweet barrel move from the Cushing to the Gulf Coast, net of the tariff they paid to get it there, it was selling for less in the Gulf Coast than it had been valued in Cushing. So all those things are going to happen from time to time, they're not predictable in terms of timing. We do think, and I think you’ve got your finger on in, and they are going to be recurring, and so we have taken the approach. We’re going to forecast what we know we think we can deliver on a baseline basis, and we’re certainly as well positioned, if not better, than almost anybody else in the industry to capture on those. If you look at -- if you’re trying to put a quantification of how big could big be, we’ve used $525 million to $550 million as kind of our baseline for supply and logistics as an aggregate, and yet over the last couple of years, we’ve been running closer to $800 million or slightly higher. And so, I think the order of magnitude on an annual basis is that we could probably or could potentially outperform in any given period by as much as $300 million over a year period, but it’s really a function of the details of which logistics debottleneck, which oversupply of light sweet crude or which refinery ran into a difficulty that nobody expected, I tis just hard for us looking forward to believe that everything works exactly the way it’s supposed to do and not to introduce a pun too much that the trains run on time and that there are no – there is no fog or bad weather, so I think PAA is well positioned to capture the upside. We just don’t feel comfortable trying to forecast, it looks like for the second quarter, and then if something doesn’t happen, we miss our numbers and the reality is we’ve got upside beyond our base level and our base level is a pretty attractive answer.
Darren C. Horowitz – Raymond James & Associates, Inc.: Yes, I appreciate that. Do you think we get to a point and it could be a very, very short point in time when the Louisiana light sweet actually disconnects south of WTI?
