Not since.. quite a while.. but earlier I loved to roam through old cities, like Amsterdam or Brussels, getting 'not to worry' lost a bit. Last time was Antwerp, about 1½ years ago. (I like that anonymous and carefree state I tend to have those days)

The next person has visited nice old cities like Paris or Prague.... and likes doing that. (well, the crowdedness is less likeable sometimes maybe but.... )
