It seems official: In the wake of Evo Morales's visit to Zürich last week, Joseph S. Blatter has granted what is for now a temporary exemption for the city of La Paz, Bolivia, from the new ban that prohibits official matches from being played at an altitude of 3000 metres and above. The final decision has to be made before September, before the start of the World Cup qualifiers, although it seems to be a done deal, as 9 of all 10 South American football asociations have expressed that they'd be fine with playing in LPB. If La Paz's exemption becomes permanent, the only city in South America that will remain affected by the ban will be Cusco, Peru.
Finally a wise decision by Blatter. Granted, Cusco hasn't been given the same exemption, but still, I'm glad that there may be a permanent exemption for La Paz.
