Currently in Calais, encountered three blockades. One was at Marquise, where we normally fuel up, the roundabout before Intermarche they seems to be settled in for the long haul with braziers (hope I have spelt that right) and shelter. Really pleasant protesters who were apologetic for any delay, there was none. The fuel station at Intermarche was closed in support of the protest.
The second was on the A16 at J44 was held up for about 40 minutes by a well organized barricade, again never felt intimidated by the smiling protesters.
The third time was at Auchan Boulogne by four ancient protesters at a pedestrian crossing who took 5 minutes to cross the road, but smiling and waving as they crossed. I think that was as fast as they normally walked anyway.
