Using ISO 3166-2 abbreviations, you may also tag the Maakond 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 Valga maakond is a subcategory of Category:Meetup in Estonia. The subcategories should be sorted in by their respective code.
