“What are men to rocks and mountains?” ― Jane Austen, Pride and Prejudice
I wanted to buy some rock slabs for a couple of projects I was working on, so I decided to check out SWB, Southwest Boulder & Stone, located at 20772 Indian Ocean Dr., Lake Forest, California. They also have locations in San Diego, Fallbrook, Cathedral City and Indio.
I thought it might be expensive, but they sell this stuff by the pound, which makes a thin slab or two very cheap. Much cheaper than a comparably-sized bonsai pot or dai. I pick up a few and I am sure I'll be back for more before too long.
They also sell decomposed granite cheap. 500 pounds for $10.
