Gay Maps of Buenos Aires

I have a collection of about half a dozen gay maps of the city of Buenos Aires. With one exception they appear to be produced on the principle that a business has to pay to be included in the publication and to be shown on the map, and since not all businesses can afford to include themselves in each and every map so nearly every map is deficient. (On the other hand, one map - GMaps - has so many dots on the map it looks to have a disease; many businesses on there have only a very tenuous connection to the gay life here and so the map can be quite overwhelming and somewhat misleading.)
The exception (and IMHO the best map) is the one called BSAS Gay produced under the auspices of the government of the city of Buenos Aires which shows all of the most significant businesses and it has the clearest map. The map is obtainable at tourist information offices and in the leading gay places.
