Dry ice would be too expensive; going to a nearby Ice Cream joint defeats my purpose; I want to have ice cream out in the middle of nowhere!!� One tip from the list was to realize that ice cream at 32 F (as in packed in ice) is not the same as ice cream at 0 F (like in the refrigerator at home, which I assume is something like 0 F).

OK....salt....that's my solution I think.� If I can prepare a saline "outer bath", just enough, not too much, and freeze it hard, it will utilize that "latent heat" thingee I once learned in school.� When it starts to thaw, it will be at much less than 32 F.� What's needed is a "phase change", going from solid ice to liquid, that's where the energy is.� 

Will do a little internet research on the correct salt to water mix to allow freezing in my home refrigerator, perhaps do some experiments with little cups, and come up with the solution!� (If one exists..)� Maybe I should just go with chocolate ice cream...who doesn't like a cold and somewhat sloppy chocolate shake in the middle of the desert...doesn't have to be rock hard, right?

Dry ice is pretty easy to find in cities, I think (I've only bought in
Boston).� A few lumps in your cooler will keep your ice cream very frozen
for at least 24 hours, probably more.� I've bought it in order to Fedex
people ice cream from time to time.� The ice cream arrived the next day hard
as a rock with lots of dry ice still steaming away.
