If you are really into interviewing you might want to participate with a friend or a relative in storycorps:
On the website you can listen to "extraordinary stories from everyday people" and find out about how to participate. They have a booth at Grand Central station for example where you can go and record your conversation or interview as well as tips on how to record your own interviews...the interview checklist is quite useful (even though they recommend different equipment to us): http://www.storycorps.net/participate/do-it-yourself_guide/interview_checklist/
