Ideas needed for using rocks in backyard.
I have a lot (200+) of these rocks (not sure what kind they are) in my yard. They are irregular shapes and range is size from 2" x 6" to 8" x 14". I'm replacing them as border rocks and need ideas on other uses for them. Can these be used for a fire pit? seating area/small wall? Because they aren't flat, I'm not sure what to do with them. Please help!
