Can i trust my Girlfriends safety?
To answer your last question first: In South Africa we have strict laws regulating the possession of fire-arms and you shouldn’t even consider that route. Johannesburg is not the third world city some people believe and private transport is extremely reliable. You will find dozens of companies able to provide you with a rental vehicle at fairly reasonable rates. You shouldn’t be too concerned about her safety. If she keeps some simple common sense advise in mind, she should be fine while visiting South Africa. If the private wildlife reserve arranged for the volunteers to be picked up, she would be as safe as anyone else in South Africa. As for emergency contact, I would suggest she purchases a pay as you go cell phone card at the airport and provide you with the number before she departs the airport building. That way you can stay in touch via text messages.
