Yes. Of course, you want to drive on fleet utilization and if you all -- this isn't an SEC number, but over the last 30 years we've probably had a net increase of fleet utilization every year; Jason's not nodding his head or not, but I've contracted with, it's pretty close to that, so that's where the economics are, and also we're kind of driven there Jamie, just because cost of equipment is always rising, wages are rising, you just -- the place to take it out of its better utilize the fleet, and of course if you ever rent the fleet seven days a week, you have to hire armed guards to take money off the bank. So, we kind of get that and we do have locations that run every equipment, every day of the week. But, that's not the norm, but we know basically -- we know how to run at that level, so there's a lot of scheduling and things involved to run at a higher utilization level and most of our systems would facilitate that. So, what we're looking -- what little unknown here right now is the distribution of the fleet. Like I said, it's kind of creeping towards the center of the country and so, we're getting great utilization, but at a point we're going to get maybe too much in the center of the country and we won't have enough outflow and then, and so we have to be kind of careful there and selective where we're sending this equipment, and we're sorting through that as best we know how, it's just a constant process. So yes, we don't need to expand the fleet to do more business, that's what you saw here. Now, we kind of held fleet because your fleet can also be determined by how many trucks you sell. So, you saw truck sales were down so because the gain on sales were down, you saw that.
