we actually found a lady on craigslist selling it, didnt look like that much till we got there, ended up getting 2 big truck loads for $100.
sizes of the rocks range from 3 ft long to 4inches long, more big than little though. we came out very good, although i had to pick them out of where they were and then bring them home and lay them. easier if they were in a pile, but they were still stacked along side a driveway/ flower bed where they were originally put.
