My husband and I bought a lovely 130 year old house. It was 110k and has three bedrooms and is in fairly decent shape considering its age. One of the previous owners was a hoarder / clepto. and has every kind of rock / paver / brick / cmu strewn about the yard. It makes the yard very hard to maintain and I have killed two different lawn mowers because of it. So now we pay someone to cut it but I want to fix the problem. What would be the best way to get rid of all these rocks / pavers / bricks / CMUs ? We have had the house now for three years and while the yard is in better shape then we got it I would like to hurry up the process.
