It’s a sad day in Gettysburg today.  Our dear friend, Bob Mullen, died this weekend.  For the past three summers Wayne and I traveled to Pennsylvania to tour the Civil War battlegrounds.  Because Bob was on oxygen, we often sat on his back porch and listened to him list  battle details.  Bob was a renowned Battlefield Guide and will be buried in his Guide uniform.  We will miss the man known as Mr. Gettysburg.  He was a true historian and good friend to us.
