Walking Town Lines

There is a custom in New England For each town to well define The boundaries ‘tween adjoining neighbors By walking down their common line. Lines firm for ages, lines well agreed And yet somehow they feel the need To get together each seven years To walk together and calm their fears That markers set had crept unseen And moved the lines that lay between And yet the walkers always find The lines intact and ease their mind Towns connected, the bounds secure Confirming lines as they once were Friendly neighbors depart their peers To meet again in seven years.
