After arriving at my campsite that evening I discovered that I forgot my passport and my adapter at the hotel, oops!
So the next day I hitch hiked back to Laon and then to my next destination at the Benedictine Convent in St. Thierny.
I've become a hitch hiking pilgrim for a day all because of my own stupidity!
.....well at least I met some interesting people along the way ;-)
