Well, Bob's got some numbers here to review. But, look, I think the majority of the heavy-duty truck space is moving towards CNG, not LNG. And, I mean, that's it in a nutshell. I mean, you're seeing more as this market has developed so far, still think there may be some LNG, as it gets a little bit more mature, out of route-type deliveries, sleeper cabs could avail themselves to LNG. But the industry has made tremendous strides on the fuel package, on board the vehicle, the range of CNG, the delivery of CNG in the urban areas, as more trucks overtime kind of the truck getting truck drivers at home at night has led to slip seating and has meant kind of more super regional trucks than out of route type, what we used to think of a truck driver or truck driving. So, I think CNG is a very super competitive fuel. And so more of it is, going to CNG than LNG. And look, we've had to make adjustments. I mean, there's no secret here. I mean we built some LNG stations years ago, that10 years ago now, right? Probably, too many. And so we made adjustments to that. We've -- and good news is we can make LCNG, right? We can put in some vaporization equipment to have CNG at our stations. And in some cases, we've had large fleets. We have great locations, right? And so, we've made the additions where we needed to, based on customer demand to put CNG in.
