Possible Interviewees

Since I am writing my ethnography on senior citizens, I thought that it would be useful if I went to a public place, such as McDonalds or Wal-mart at times that seniors tend to dwell there. I could also go to a bingo hall or an actual nursing home. It is also possible to get useful information from people who aren't exactly seniors themselves but know them well. I may have to go the extra mile to get this information, because I don't have the benefit of having grandparents or close relatives who are of that age range.
