getting from point a to point b

i'm leaving on monday for africa to visit the order of the holy paraclete at their house in swaziland where they run a girl's orphanage. i am flying into johannesburg. flights to swaziland are sold out (i'm imagining a 10-seater plane made of balsa wood and rubber bands). there's a backpacker bus tour that goes to swaziland - the last bus leaves at 9.15 a.m. and i arrive in the jo'burg airport at 8.35 a.m. there are minibus taxis but they seem dangerous at best. the vans are in bad condition, the drivers are insane, they don't go direct but will drop me off at a location and tell me to change buses. meanwhile, i'll be alone with a u.s. passport, money, and a vagina. the state dept. and british home office websites basically say that if you're a woman you'll be raped as soon as you set foot in jo'burg. great.
i'm a seasoned traveler but this is nervous making.
so, please pray for me to get to bulembu in one piece with my passport, money, and hoo-hoo intact.
