Today - two bits of bright mild steel slab, wood for about one night's heat, some straw for the primary school Christmas stable, and some 'interesting bits of wire' with banana plugs on the end
Most recent electrical find - a string of 20 240v weatherproof festoon light fittings, British made, apparently sells for about 100 quid, and apparently new. People are very strange.
(But David - sometimes yes it's just soil and broken bricks!)
