From Memory Alpha, the free Star Trek reference

I watched TOS as a kid in the 60s and became a hard-core blue-shirted trekkie in the 70s, going to my first con in 1975. I'm not as hard-core anymore, mainly just watching it on TV and the theatre. One thing that I have retained a particular interest in is stardates. --OhEidhin 03:17, 24 January 2007 (UTC)
