[Highland Park] Scraps of flat stone or pavers?

Dear Neighbors, We're looking for scraps of flat stone and/or pavers that you may have been meaning to throw out! We've just put in raised garden beds, but since our yard is uneven, need some stone to fill in between the ground and bottom of the beds. If you have some broken or left-over pieces from a project, I'd be happy to take them off your hands. Of course let me know if you $ or some other barter for them. Thanks, Dawn
