The gist is that the French security forces are shutting down the impromptu "bars" (kind of like off-licence places I guess?) that have popped up along the route for the last few years. The zone in which these establishments are banned includes, notably, "4 cobbled sections, the most important ones at the end of the race." I assume this means one can still bring one's own booze? Anyways just thought I should warn the PdC contingent!
