Next time you need a place to get away (without burning oil) try planting beans. Many varieties will grow to cover a trellis such as this one. Imagine spending a couple hours one afternoon to rough up the soil around your favorite bench in the backyard, putting up a few poles and some loose netting to about 5 or 6 feet high, then planting edible beans. In a month or so you'll have a verdant getaway, a green hideout. Soon after, you'll be surrounded by food - dried beans.
