One trip, seven capitals, three weeks

On my most recent tour of Africa for fun and profit I may have set a record for capitals (the places, not the typing):

• DC, capital of the US (noisiest)
• London, capital of England, the UK, and Great Britain (worst weather, best beer, worst food)
• Nairobi, capital of Kenya (worst traffic, best hospitality)
• Lilongwe, capital of Malawi (least developed, cheapest)
• Johannesburg, capital of South Africa (best airport posing as shopping mall, most biltong)
• Mbabane, capital of Swaziland (smallest, best scenery)
• Gaborone, capital of Botswana (most fun compatriots, most boring city)
