Nancy and I are avid sightseers so we decided to stay on and see a little more of the city.
Almost from the beginning there were occasional sightseers and, more remarkably, women.
Barbed wire on top of a fence is offensive to the sightseer.
It is deplorable when large crowds of sightseers make it difficult for ambulances and the fire services to get through.
It is a place to which sightseers go from all over the world.
I submit that unemployed men and women have as much right to be in that crowd as anyone else as individual sightseers.
