Heathrow. 36 hours straight of no sleep. So knackered. Walked London all day for 8 hours. Met a group of folks with UNHCR, WHO, and UNAIDS also headed to Africa. Great chat. Swell lunch at The Groucho Club with Fiona (Russell's lovely sis.) Heading out for the 12 hour flight to Jo'burg, South Africa. Finally, Africa. - G.
