when the evening was slow or Sunday during football games, I'd look thru them to see what all a company carried or went down to the performance rack and dreamed about which parts to order.
Same here. Slow nights, rainy/snowy days, early mornings...anytime it was slow. Made the time go by faster, and I got to learn the books better, which was a win-win for me., as we couldn't look things up on a computer back then.
And I hate to come-off as bragging, but I got pretty damn good at it!
