Of course, having gone as far as Arras, we then decided to retrace our steps slightly when we discovered there was a preserved railway at Le Crotoy! So the morning was taken up by a pretty drive across country, visiting various small villages en route, and a supermarket, and we would have liked to have visited the Abbey church of St-Riquier, but it was closed until 2.
So we had lunch in a community centre car park somewhere, and then headed on to Crotoy, where we parked rather badly (and got a ticket - they say they will send it to our home address, so no point worrying until we see whether they do or not) and went off to the narrow-gauge railway.
The railway runs as far as Noyelles-sur-mer (it isn't at all on the sea, so don't know why it's called that), and then swaps engines with the other train and heads out backwards to St-Valéry-sur-Somme, where there was just time to stretch one's legs and take some pictures before the return journey. We made sure to sit in a rather more comfortable carriage on the way back - the plain wooden seats were not the most comfortable ever; the padded ones were marginally better!
After that, we had a much-needed cup of tea, and then decided to come to this place - a France Passion place in a meat-preserving factory! We drove via Crécy, and made a brief detour to see the site of the eponymous battle, which is basically a field full of cows, although there is a car park. We decided not to stop, but came on here. The shop is, thankfully, closed, but we were warmly welcomed by the proprietor, who wished us a pleasant evening.
