Fishing on foot in the Bay of the Somme should be an Olympic discipline, “survivor” category. First, you have to put on boots, walk for hours in the mud and bend down all the time to cut slippery marine plants with a mop. Then you have to put them in a bucket that is regularly emptied into a big burlap bag. Finally, you have to carry it all on your shoulders with the tide biting at your heels like a hungry wolf ! But according to the bay’s gardeners, the experience is worth all the sacrifices. First of all because marine plants are soon rarer than diamonds. The best known of them, the glasswort and the sea aster, grow almost exclusively in the Somme Bay, between the Hourdel lighthouse and the Crotoy. Then because with its Henson horses galloping under a reddish sky, the Marquenterre gives you back a hundredfold the efforts you made.
