LOLs you know i know all that, i hope. If it were really necessary, for a beach get together e.g. to keep beer or other cold i'd be into it, but if i can manage to get frozen peas home cold enough to be slipped into a freezer again then i'll stick with my good old totally collapsible, comfortable and convenient squashable green bags. For bananas or raisins sake, I can put them into a jacket pocket. You do understand, i know you do too. LOL
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
