Personally I find their street signs much better than we have here, in
that they appear at every road junction, with both streets and the
block numbers on them. Here it is unusual to find a street name at an
intermediate junction.

What threw us, until we got used to it, was the way they put the name of
the side street across the street you were on; until we recognised the
convention, we kept on thinking we were going to have to turn! But it
*is* clearer than ours, certainly, although I'm told it does vary and in
some states is much less clear than others.

The clearest street markings I've come across in Europe were in Poland,
where each house seems obliged to tell you not only its number, but also
the street name.
