Just put a couple of hogs in the freezer last month.
Should run out by next year, but will have some more.
Ya suppose the airlines will let you carry on dry ice and a center cut?
Probably not, since they make such a big hairy deal out of moving it as cargo:
Carbon Dioxide, Solid, 9, UN-1845, PGIII
Passenger aircraft maximum permitted quantity 200 KG (440 lbs) flying under packing instruction 904.
IATA Packing Instruction 904:
Carbon dioxide, solid (dry ice), when offered for transport by air, must be in packaging designed and constructed to permit the release of carbon dioxide gas and to prevent a build-up pressure that could rupture the packaging.
The net weight of the Carbon dioxide, solid (dry ice) must be marked on the outside of the package.
Arrangements between shipper and operator(s) must be made for each shipment, to ensure ventilation safety procedures are followed. The Shipper's Declaration requirements are only applicable when the Carbon dioxide, solid (dry ice) is used as a refrigerant for dangerous goods tha require a Shipper's Declaration. When a Shipper's Declaration is not required, the information for the Carbon dioxide, solid (dry ice) must be contained in the "Nature and Quantity of Goods" box on the air waybill, excluding the packaging instruction number and packaging group.
Maybe you should just not mention it to anyone. ;-)
