I checked out new construction subdivision sites on the weekends, tons of rocks everywhere and the price was right too, LMAO! Just dont go right after it rains or you'll be ankle deep in mud lol. Many subdivisions are actully using the rocks for landscaping so make sure you hit them before the houses are starting to get close to finished. Get some ibprofen before hand. 100 lb + rocks look nice, but your back will thank you for it after .All those rocks came from my brothers back yard he just build a new house and there were rocks laying around everywhere so I just helped my self to them, and now my back is killing me.
