Let me start on the public sector side. On the public sector, what we're seeing is a lot of uncertainty and delays in terms of expanding CapEx, mostly related to, "Where's the money?" So it's a combination of issues with getting bonds out there and funded, with tax revenues, both gas tax and sales tax at the local level, and gas tax at the federal level. It's a function of the Congress and their reluctance to commit. There's this idea that we did stimulus, so we don't need to do anything else. And frankly, if you do stimulus and you don't do anything else, you seem to just didn't fill up the hole that you left by not doing the things you would have done anyway. So there's a whole combination. Now that's true here in the States, it's also true in the U.K. I mean there's a very significant budget problem in the U.K. as well. There's a move out there that turned down budgets by 20%. That's bound to affect both the government spending and the national government basis and at the county level. And so it's a market where it's really a funding uncertainty. Where is the money going to come from? And to a lesser extent, a revenue uncertainty. How are we going to tax enough money to get what we need that's driving the numbers? On the private sector, I think it's a more just good business or maybe not-so-good business, so maybe I'll call it a crisis of caution or a crisis of pessimism. But most of the customers I talk to have significant number of projects that make financial sense at current oil prices or depends on what market they're in, obviously, but who are going to commit to those projects and very slowly, because they don't have confidence that the recovery is real, and I think we all suffer from that to some extent. We see what the Street and the press, more than media than anybody, is saying about the growth numbers, and you don't feel it in the economy. And so, I think, a lot of our customers are being pretty cautious. I think particularly when you get up in the Oil Sands, you're seeing the customers sit up there that sort of once burned, twice shy. And they are all collectively very reluctant to get all their projects up and going, and find out they're all doing things at the same time and have the market run away from them again. And so, I think, that's also driving a sort of a stepwise approach in a fairly cautious CapEx plan going forward.
