Yeah, good question. I will tell you that those frac crews and the drill crews, by and large, are hardy, hardy guys, and women. They are out there 24/7 through the winter. And being out there 24/7 over the last three days, where it hasn't gotten above zero here, is hazard pay to any measure. But, no, they do frac. Water tends to get a little stiff at those temperatures. And so, they do actually preheat that. So they heat it coming out of the reservoir before they put it into the line, then that line just is laying on the ground. So, it's fully exposed. And it gets snowed on, and it's a complicated venture for that. But they are flowing at quite a volume. They're flowing as much as 4,000 gallons a minute. And so, when it's flowing like that, it has a tendency to stay liquid, and then they want to make sure that they get that continuous operation. And it's part of that technology of the fracking, once you're in the hole, you kind of have to keep through that hole. So, we are continuing to frac. As far as the Q2 cycle, I'm pretty optimistic that Q2 is going to look a lot like Q1 and Q3 and Q4. I hope we're going to look like Q1. The thing about the oil and gas companies is they pay you to be at their beck and call, but they don't always call. And so, I think that the stability of the regulations here in the Colorado market are lending themselves to continued investment by oil and gas industries, as well as the strength of the oil and gas market. While it isn't as good as it was at $100 a barrel, I think these operators are very comfortable continuing to make their investments at the current rates. And I wish I had an idea of what dollar number that would turn off or speed up, but they don't share that information other than the fact that they've given us a projection that would continue to support similar results to Q1.
