Re: Rocks from Lowes - possible waxy coating?
@Judy: what problems does gravel have? I'm not aware of any :x
What is "decorative rock"?
perhaps my reference to gravel was poor, but if you go to a "building supply store" you can usually find ALL kinds of rocks for extremely cheap
Off the top of my head, I bought 42 pounds of slate rock and ~20 pounds of large river rock (perhaps thats more what the OP was looking for?) for less than $10.
