Zambian/Botswana border

Forgot to mention that there are lines and lines of transport trucks on the Botswana side of the border waiting to cross by ferry into Zambia. They can take about 50 a day and often they have to wait 2 to 3 weeks!!!! to get across. They are prepared with food, etc. but I gather that the Zimbabwe women come over to this area as prostitutes. So that's one way AIDS gets spread. There were shower facilities for them.
