Thats how I learned the sort too! the days before PAL Labels. I couldnt believe how many guys they let go, because they couldnt learn the sort! OF course way back when.....it was a really good part time job! Plus my girlfiend at the time, would play strip flash cards with me! EVERY time I would get it right a peice of her clothing would come off. You wouldnt believe how fast I LEARNED IT!...lol
