Yeah that's fair. It does make me wonder what there is that would allow this. Maybe importing some snow machines from Tahoe? :-)

I'm actually a little surprised that a quick search for "refrigerated liquid transport" didn't turn up anything. I would have sort of thought this was something that would exist (just because there are so many random things that are necessary for _some purpose_).

Snow machines are just big spray nozzles. They don't chill the water the way you might be thinking. There's some adiabatic cooling from the expansion of compressed air, but that's about it.

Refrigerated liquid transport absolutely exists. Milk trucks is an example off the top of my head. Liquified natural gas is another.

Well, "Ice Cold" water is ice and ice trucks are a thing - not to mention for fast substantive cooling 0 Celsius ice blocks on top of the tank would soak up far more heat energy than the same weight of 0 Celsius water.

As for the transportation of cold liquids, there are many LNG / Propane trucks about - pressurised containers for Liquefied Natural Gas.
