I started visiting the European battlefields in1990 initially with war diaries, guide and text books, trench maps in my hands, on my lap, on the steering wheel and on the spare seat, getting sometimes lost and annoyingly confused.
Later, when taking groups of friends on tours, my sense of direction had improved as had my ability to rely on fewer and fewer books, my confusion became a thing of the past— at last I knew which way the enemy was coming from! And I found where the good bars were.
