This was a lot more work than I anticipated. I dug the trench (7ft x 21ft x 1ft), and my father in law came with a cement mixer and some fence-making know how. After two weekends, it's finished! Kind of. I need to paint it to match the fence, fill it with garden soil, and plant. Hopefully, I'll do all that this weekend. I'm excited to have a large garden area, though the kids will miss their large 'sand box'.
