Yes or No to yardage book/scorecard holders? and if yes share yours ?

never used one don't see the point, if i'm ever visiting a new course i do the same as above and stick the card on the rel page, if i'm in a comp and its raining at my home course the cards goes in th eback pocket of my waterproof GG jacket, i think thats what its designed for.

just more clutter to carry with you TBH
