That is funny. You would make a good "dumpster diver".
I have a young girl that helps me and she also works for a few
businesses like landscaping, etc and she goes thru their dumpster for pots and greenhouse stuff for her place. What a riot she is. One day she took me with her to dumpster dive and we got lots of goodies. Those landscapers throw all the pots away when they do a job. I would think they could return them to the wholesaler they bought the shrubs from. Hmm. Just thinking outloud.
