Things like logs and dirt are not really laughable to me. If you're undertaking a landscaping project free fill dirt is a great find. It's that or pay for it and if you pay for it takes money away from the rest of the work you plan on doing. As for wood (logs, pallets, whatever) people use these as fire wood to save on energy costs in the winter and a free log you have to cut up is a lot cheaper than cords of wood. I've also used logs as benches in artsy landscaping projects. Where most would look at those as trash others don't. It's all about seeing things for what they can be and not what they are.
