Here's Dad's garden, prior to the greenhouse. It's on a south-facing slope, behind the house, which is good for sun, but the direct sunlight during the middle of the day caused a lot of wilting in the lettuce and spinach and such that he liked to grow there. Plus, the local elk, deer, and rabbits who frequent the backyard would also make short work of eating everything -- hence the elaborate and quasi-functional netting system over top. All of this, plus the short growing season, meant that these raised beds weren't really cutting it.
