Walk the balance

The reader of ABC news says Trump needs to "walk the balance" between Iran and the US in the latest incident with Iran in the Middle East.   Who knew but me that the unbalanced news can't 'speak' English properly?   So on to real news.  Who knew that ladies in the Middle Ages tamed squirrels as pets which acquired significance as representative of the penis.  'To crack a nut,' the squirrel's undisputed skill, became an established metaphor in poetry for sexual intercourse and was clearly understood by the grammatically adept giver of a clever, wooden love ring popular at the time.

Another popular item in the 13th century was  a love brooch.  "My bride shall wear a brooch, " etc. This poetic ditty explains:  "Take care not to allow your breast/To be felt, fondled or caressed/
By any hands save those that might/ For, true it is, when one first thought/
Of fashioning the clothing clasp,/It was to keep man's lustful grasp/
From woman's bust, which should be known/ To husband's hands and his alone.

The Middle Ages set the precedent for us too with  their 4 most popular pilgrimage sights - the shrine of St. Thomas Becket at Canterbury, Rome, Santiago de Compostela and Cologne.  You ask what are our pilgrimage sites today?  _____________________ Fill in the blanks, please.
