I've been going to the plant sales since I heard about them, and taking Randy's tours before hand. Last fall I joined and looked forward to a long relationship with TDG, with more time spent upon retirement. I've been involved with organics and native plants since the early 70's in Austin. Upon moving back to the area, I had the pleasure of learning from Rosa Finsley at King's Creek Nursery. When they finally shut down, I was saddened by the wasteland that is Dallas landscaping. Then I discovered TDG with lots of plants that are vital to sustainability, but not commercially viable. Randy had lots to teach me. I doubt that you can replace him and his knowledge.
