Looking for leads on locations and availability for some different varieties of decorative rock. We currently get our black trap and Merramac from Missouri. Washed gravel and bark mulch is available locally. Would like to add a couple of more varieties to our selection. Anyone have any info on quarry locations in Indiana, Missouri, or Southern Illinois? What do they have available? We have a local guy handle the trucking so delivery is not needed. Thanks for any help.
