Mel , of course it depends what chemicals they do use , but Salt and calcium chloride are bother totally natural chemicals actually occurring right there .
Nan , when we left Mata mata , we drove over the northern dune road , and I actually stopped at one place and measured the corrugations and , and at that point they were around 15 to 20 centimeters deep
Try driving a vehicle over that
Well , enough of that

Next year , we are going to Etosha

If I am forced to drive sand/dirt roads all the time , then at least I can go to a country where they know how to make beautiful roads
