There could have been a quad-point where four countries' borders met in the middle of the river, but NOPE Botswana just had to have an extra 150 metres of border between it and Zambia to split Namibia and Zimbabwe apart Such a let down. Therefore I have no choice but to give them 1 star.
The four corners. On each corner is a Starbucks sub station!
