Yes, that's always a good question. And the fact is that in San Francisco, there are some people besides us, obviously, that want to seek entitlements, but there's very, very little land that's going to be available to develop. It's going to be very restricted with Prop M over the immediate future. But as long as I can see at this point, unless all of a sudden there's a correction and there's an accumulation in the bucket, like there was from 2000 to 2010, I don't see that on the horizon. Seattle, very, very little land available in Downtown Seattle and South Lake Union. There are a few more opportunities in Bellevue. In the markets that we're acquiring land or have acquired land, there is such a strong barrier to entry that I think it's more a case of having something that others need, and that your competition has a real time replicating. So I like that. The question about developing, a lot of development wants, to me, to your point about a ceiling, I think it depends on how we're feeling about leasing. As you've seen, with The Exchange and with Hooper and the way we played 333 Dexter and so forth, I don't think we're getting over our skis. We've maintained one of the two or if not the most conservative balance sheet. I'll put our balance sheet against any of our major competitors in the public arena. And we're not going to get out of whack on our balance sheet. We're not going to get out of whack on developing spec space. I know there was a lot of questions and maybe some concern about Kilroy with regard to The Exchange. And all along, I've said, "We'll have this leased at a pro forma or above before it is delivered." It's not going to be delivered. It's not going to be delivered now for, what, another six or eight months, whatever it is. Tyler can give you the specific date. And we're going to do what we think is in the best interest of our shareholders. Obviously, if our shareholders think we're crazy to be accumulating land or are crazy to be developing, then that's going to be reflected in the way we conduct the company. But we also have something that most of our competitors don't have, and that is we have the capability to develop world-class assets, to assemble difficult sites, to get entitlements when few others succeed, as we do, and deliver on time and on cost at terrific, superior yields. So that, to me, is a strength that Kilroy has, and we want to play to that strength, but we're not going to get crazy. We're very, very disciplined. So I'm reluctant to give you hard numbers or hard ceilings.
