We’re working on our garden, in a new area.  One part of the soil is darker.  We figure the builders had a burn pile there.  In addition to the rocks that are present in every garden (except Eden, unless God wanted Adam and Eve to sit.  But I digress.), there are metal bits.  Nails, mostly.  A couple dozen of them, and wires.  We’ve found probably close to 100 nails from this little patch of the garden, just a few square feet.

I wish the builders had been more careful, or cleaned up after burning the wood.
