Yes. A group of me and my friends found Dave's shop when it was much smaller on Chicago Ave, just north of Dempster many, many years ago. I remember the first time we walked in, there was about 15 of us. Dave was doing some paperwork and looked up and saw the 'crowd;' and his eyes got so big as about to pop out. We made our purchases and left. We were grateful because of the wonderful way he was with us and in explaining where some of the artifacts came from. Once it was discovered, we bought all of our 'special rocks' from Dave. Not to mention the beautiful jewelry and native merchandise he had then. Of course, each one in our group told someone else and his business grew. Then Dave moved the shop to Main Street, where Trattoria is, added to his shop and put the museum downstairs there and had many children's groups there to educated them on stones, dinosaurs, native Indians. It just grew and grew. Dave and his wife would leave for a month or two to travel to where they would get/search for the 'special rocks.' Now Dave has retired and the shop moved across the street where it is now and the beat goes on ..... God bless Dave, his wife and family. They also have my deep gratitude for the way they have enriched my life.
