If your yearbook is old enough, consider googling "[name of school][year] yearbook" -- I discovered that there's a library with a collection of yearbooks from my high school, and they didn't have my year (1972). ~ Not sure where you reside, but in in the US the donation might be considered a charitable contribution. (You might save enough on your taxes to cover postage. :p)

I went to HS in the mid-70s, and was primarily known as a hardcore Bowie fan during that time (I was the first to chop off my long, ironed-smooth hair in favor of a Ziggy mullet). Though I'd been a Trek and general Sci-fi fan for years, it wasn't until I moved away to college that I got into fandom.
