Last weekend's project was building this (almost) 3 foot by 4 foot elevated herb garden, and planting
sweet basil, cilantro, rosemary, Italian oregano and flat Italian parsley. It was so heavy we had to move it from the garage to the back yard, taking three short rest breaks and barely getting through the extra-wide gate, before installing the 2'x4's that make the floor. Add the garden soil and I'm estimating about 500 pounds.
Here's hoping those fat rabbits can't jump this high. Next step will be calling Elmer Fudd.
