Extra tentsExtra tents have been set up in case it rains and up to 200 buses are being "mobilised" to transport revellers, who will be hoping for a taste of birthday cake and the 150 cattle donated for the occasion. Zanu-PF secretary for youth affairs Kudzai Chipanga told the Chronicle on Thursday: "We have already secured accommodation and food for everyone, including those who will arrive early."Schools not closed A controversial decision to close schools in Bulawayo and surrounding areas on Thursday and Friday ahead of the party was revoked on the back of widespread anger, according to Raymond Majongwe of the Progressive Teachers Union of Zimbabwe.The hundreds of thousands of dollars spent on the festivities provokes outrage each year, given Zimbabwe's fragile economic situation. The state ZBC broadcaster reported on Wednesday that $14m was needed to repair recent damage caused by tropical storm Dineo-linked floods in Masvingo province alone - and the damage has been considerable in other southern areas.Swiss surveyBut some Zimbabweans have found another focus for their outrage: a suggestion that their "City of Kings" Bulawayo is actually the worst city in Africa in terms of housing, infrastructure, governance and the environment. The BBC reports that the finding is contained in a survey by Swiss researchers from the Ecole Polytechnique Federale de Lausanne.The official @CityofBulawayo account hasn't responded yet to the slight.

I call Bulawayo the world's best kept secret!"Have you ever visited Bulawayo? What do you think of this survey?
