there are a couple of different approaches. One is to create categories for every conjunction of categories - if you have "hotels" and "museums" and "Ohio", that means you should have "hotels in Ohio" and "museums in Ohio" categories.
I favour this approach. Without it, [[Category:Museums]] would contain *all* museums in the world (millions!), and [[Category:Ohio]] would contain absolutely *everything* about Ohio (cities, museums, exhibitions, operas, theatres, cinemas, railways, bus lines, sightseeing, TV stations, and all sorts of other unrelated things).
That is simply bad database design. A user should be able to select [Museums] WITHIN [Ohio] or just [Museums] or even just [Ohio]. Otherwise different tags will be needed for all possible combinations of museums, sport stadiums, or amusement parks in every single area of the world. It would be much better to have tags for the places and tags for things. Let the user decide what combination of variables he or she wants to select. That will require an advanced search capability to be added to MediaWiki, but I assume that was planned anyway.
