FYI, we are a 60ish couple who have car tripped all of North America
and Europe

I thinking of a visit.

Flying in to Johannesburg

A few days in Johannesburg

A few days in Krugher National park

Renting/leaseing a car in Johannesburg

Drive to Cape Town

A few days in Cape Town

Drive the coast to Durban

Drive to Johannesburg

Fly out of Johannesburg

Have I got a good start on where to go?

Is a month a good amount of time?

Is this the right time of year?
