Use {{location|PR}} to tag expeditions that took place in Puerto Rico. It will add Category:Meetup in Puerto Rico to the expedition.
Using HASC abbreviations, you may also tag the municipality that the expedition took place in.
If the category link appears red, do not worry and create the category. Make sure that it is included in the appropriate parent category, for instance, Category:Meetup in Maunabo is a subcategory of Category:Meetup in Puerto Rico. The subcategories should be sorted in by their respective code.
