Sounds like an excellent idea, maybe you could send some plans and instructions to the OP and they can find a much more productive use for their time.
With pleasure, Mr. Casper...
1) Get four (4) 8 foot long X 1 foot wide X 2 inch thick planks.
2) Cut 2 feet off the ends so you now have four (4) 2 foot long end pieces and 6 foot long side pieces.
3) Get a small box of 3 inch long TORX head (T25) deck screws
4) Screw the side pieces onto the end pieces to make a nice 6 foot X 2 foot bottomless box.
5) Paint them a color you like, and decorate the sides with whatever pretty designs you prefer.
6) Line the inside bottom of each box with black sheeting anti weed paper, then dump garden dirt into each box, and let your cats play in them for a few days so they are no longer a novelty cat toy.
7) Plant seeds for beans, peas, melons, squash, or whatever you like to eat and watch it grow.
This way in a few shorts months you will have something yummy and nutritious to eat that you grew yourself, rather than a silly post people will be making fun of you about.
Your blood pressure will be helped through the actions of building it, humping and dumping the bags of garden soil in them, watering and deweeding them, and finally eating the nutritious produce you just grew.
Of all the forums I have been on, and of all the many hours I have expended making posts and countering other people's post.....I have yet to see any awards given to "winning" a flame war, or putting anyone in their place on a thread.
Conversely, I HAVE reaped the benefits of working outside and doing things that matter in your small corner of the world.
