Sorry, I am not seeing the downside!!

suggest you serve drinks indoors so when you entertain know one knocks their noodle off of those rocks

Hello! Yes, there is a market for granite boulders, especially if they have moss or lichen growth. Look for "stone centers" that supply rock for paths and walls, or large, independant nurseries in your area. Call them and ask if they want them. You may not get cash for them, but you may get them hauled out for free. Waterfall designers are also a good place to try.

The problem is that most people do not have the means to transport those rocks. I agree with nativenut that you probably should call independent nurseries who often sell landscaping boulders. They'll probably pay you something.

Mike, sounds like you're talking about my place. I have roundish pink granite boulders sprinkled all around my yard. At least mine are a managable size, between soccer ball and basket ball size. I was thinking of selling them at my garage sale next spring. But you might try listing them for sale on something like Craigslist. I have no idea what rocks cost.

Maybe somebody on this list lives near you and would like them (or mine). :)

Mike, How I wished you were out here in California! I have been rock buying little by little every week, in my trunk, as I am using them for edging. Goshdarnit!
