Address: 30 Petrova Avenue
Old Address: 64 Petrova Avenue
Other information: In the 1970s and later, 64 Petrova Avenue housed Ralph Bristol's small business, the Adirondack Rock and Gem Shop in the basement. Kean and Kasey Riley, who lived next door at 60 Petrova Avenue, developed their initial interest in rocks from stopping in at the neighbors' house; later they started the Twin Crystal Rock Shop, presently in the former Scheefer Jewelers building at 13 Broadway.
