text: I'm aware that there is a climbing rock here. What I was wondering is what the "yes" in climbing:shoes=yes means, because it could really mean anything. Required, recommended, sold, rented,  etc. etc. 
  
  It should go without saying that rocks don't have shoes and therefore it nonsensical to tag one like it does. Especially without clarification. As someone who rock climbs myself once in a while, it would be good if there where more specific tags for such things that were actually defined and clear. Therefore, what does the "yes" actually mean here?
