France may be the world’s most popular country for travelers, but it is also one of the most strike-prone, with protests disrupting the flow of goods and services about as periodic as the full moon. Fishermen angry about increased fuel prices shut down ports all over the country for three days the last week of August, and were immediately followed by truck drivers and farmers snarling highways, including the Chunnel to England. Taxi drivers soon followed suit in France’s major cities, so check on current conditions before venturing out on the highways.
