Wow, that brings back nightmares. My first and last home improvement project (6 years ago) was regrading my back yard and building a rock wall.

I only had 5 tons of rock, but manually wheel barrowed it all to the the back yard and built the wall and moved hundreds of wheel barrows of dirt around, all by hand. I had to replace the axel on my wheel barrow when I was done.

It will probably be several more years before the memory has faded enough to tackle another project.
