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.
