Thanks. I appreciate that.
Mr. Mouw, it was interesting when you talked about propane in North America, that it was a domestic resource, that it was something that we didn't have to buy from places where people didn't like us very much. I'll presume that you probably like ethical oil from western Canada for the same reasons.
My question to Mr. Stewart is this. You made reference to the conversion kit. That's the world you live in. I'm trying to think of how you get this beyond the fleet level to the practical homeowner level. Are the conversion kits that you have transferable? I think this is probably one of the impediments that an individual might have, because if I went from my current vehicle today and made a $3,000 to $5,000 investment in a vehicle that I was going to lease for three or four years, it wouldn't be practical for me. But if I wanted to own that vehicle, thinking I might have it for five years and then want to get something else, is that kit convertible? Can I put that same kit you put into my first vehicle into my second vehicle? How does that work?
