I was just doing some web searching on the Liesbeek and this site comes up 5th for liesbeek river and and 4th for just liesbeek
The number 1 article is the Wikipedia page on the Liesbeek avaialble here
Not much substance to it but the beauty of the Wikipedia is that anyone at all may contribute. So check that page today and check it again in a week – I will be making a contribution to that page. Feel free to make a contribution of your own.
