Well it was all so easy, download the tous covd app, put the nhs 3d bar code onto it, [3 mins] show them to the nice French customs man [ he didn't really want to see the honour statement] and drive out [another 3 mins].
I'm now down in Le Moulin Du Bel air, having a glass [or two]of Vin Blanc with a couple of old friends,
Happy days
Ted
