No idea who the two subterraneans are. I went thru the rest of the 36 pics, and a lot of them looked liked guys from the geriatric ward being taken on outings by their beautiful young caregiver ladies. I did recognize the location for # 6 (I spent a school year in a room in that YMCA long, long ago) and I've met the twin brothers in pics 11 and 12. One is a real nice guy.
