planning on buying a car
Yes indeed. That is one of the cash problems. I can't get enough out of an ATM for that. I can't open a bank account before I get there and transfer money from the UK or Greece so I am going to have to arrive with cash. We need a car as soon as we arrive. Our rented house (shack) is 15km to the south.
We have always found taxis in Maun to be fairly reasonable prices compared to here or the UK actually. Not that you want to use one all the time, no matter how entertaining it is!
