I lived in a tent for several months after moving to NC nearly 30 years ago. Before and after that, long term (3-8 weeks at a time) camping off road to gather wild medicinal plants, flowers for potpourri, and sassafras and slippery elm root bark. Lived out of the back of a truck in summer (and in winter in south Florida) doing craft shows, flea markets and farmers markets.) All on a very thin budget. Cabbage keeps. Whether in a cooler with a block of ice or tied in a mesh bag to a tree limb while camping. Lettuce and other greens don't keep well in said cooler or tied up in a mesh bag.
