Think the clue may be in the actually wording....
1: USE.....ie yoose
2: USE.....ie: yooze
SO....if you read it in those terms....YOOUSE of.....then there is no age limit for the yoose of a crabpot....whether in fact they can YOOZE it themselves seems to have gone by the wayside.
Jus the way I sees it....what do u guys think
