I have 3 15-gallon tubs of used red lava rock that I am giving away for free. It’s from an old project, and the rocks should probably be washed before you place them anywhere. Let me know if you want the & I will move them up to my driveway for convenient loading & social distancing. Please bring your own containers to transfer the rocks into. If I don’t hear from anyone within 2 weeks from now, they are getting dumped at the edge of my property.
