<img src="/images/graemlins/smile.gif" alt="" /> One more reply to Benjamin - RE: pure fat.

Read Phillip Henry Dana's "Two Years Before the Mast" (great book). In one episode he describes the Russian sailing ships in California (long time ago!) that shipped out cattle hides. Apparently, they rendered out the fat and packed it into hide bags. They mostly lived on that and, as Dana had it, celebrated once a week by cooking the bags and eating them! Could I wrap them in aluminum foil? Keep car clean and use for signalling.

Seriously, thanks for the input. You brought me back to Earth.
