...not as easy in real life as it is in my head.

We got a dump load of scrap granite, totally saved from the landfill, and used it to pave our garden.  This took about 100 hours of sweaty, back breaking labor.  Then the invasive grass from our area came and covered it up in about, oh, 45 seconds.

We now have a load of tires, also totally saved from the landfill, and are using them to build a garden wall.  The wall is (in theory) designed to keep the invasive grass out of the garden.  The base of the tire wall is also a convenient spot to dump all of the granite we are not using.

Until then, though, we've got a pile of scrap granite and yard full of bald tires. I am feeling just a little tiny bit like a dump.
