is the effort of getting my job back at rei futile?

I am wondering if it is even worth the effort to apply at REI, I was fired from there in 1998 but with no explanation why, (and I sure as heck don't know why) so I am left with this big question mark over my head wondering what happened. It was kind of like a car wreck or another traumatic experience, at the end of my shift the boss just said your fired and that was it I went to the back, got my stuff and that was the last day I worked at REI, now if that had happened now I would have contested it knowing full-well that I did nothing to get fired for. This was before 1998 so I am wondering what you think about applying again, I have moved so it would be a different REI but I know they probably keep records of stuff like that, but for how long? Any suggestions are also welcome (and don't tell me to move on, I already have moved on and had other jobs and did not lose them but couldn't stay in them for one reason or another ( moving ,etc.) , but this (REI) was a career. So should I re- apply or just give up and get some job I don't want.
