Found archival sound! Old cassette tapes from Dad to Mom.

I am in El Paso... looking through my three trunks of stuff still at my mom's home. I read through old journals of mine. I found a couple of gems from 1996-- one describing how I'd feel if I ever lost my mother and one about cooking her dinner after a long day at work (reminded me of those long days alone). I also found a box of letters from my Dad. I don't remember how I got these. I think my Dad had saved them and then gave them to my sister. She then gave them to me? In any case, I opened up the box and started going through them. Found some poetry he had written for my mom (and some she wrote for him), old anniversary cards, and THE BEST FIND OF ALL: cassette tapes he recorded for her while he was serving his mission. I am particularly excited to listen to one marked, "Honey, this tape has been given all my love and consideration - it will be best heard alone and in the dark - this tape communicates my thoughts about us. Love you very much, yours forever. Richard." I really REALLY hope these cassette tapes still work. It would be so amazing to have some audio from the time when my parents were in love. I'm not sure how I will work it in to the project (maybe in an intro part... describing how things used to be?), but it is SUPER awesome to have found these. I didn't even know they existed. Brilliant! I am going through home videos as well. Haven't found any hidden gems there, but I have secured the VHS tape of my baptism (the last real family event we had). My family sang together there and I anticipate ripping the audio from it. I haven't watched it in years, so hopefully it is useable. In crap news - I am getting sick. My voice is getting scratchy, I'm coughing, and I'm congested. It is making my voice sound like crap and I am worried that it will affect my interviews with my siblings that I have in a few days. Please bless this is gone by the time I need to record my voice...
