1. L'eau. Back then we were warned not to drink French water; now in most restaurants when we asked for water we were given a carafe of tap water. Sometimes we were offered a choice but mostly it was just brought. And it didn't do us any harm.
2. I knew I should have written things down when I thought of them.
3. Ah yes, caravans. In our day the sites were mostly full of tents; now every camp site has caravans. Some have camping emplacements but some have changed over completely.
4. Then the national French holiday was in August - I think it was like factory fortnight in the UK; now I suppose as industries change that's less common and there were many French people on holiday.
5. Toilets. When choosing a camp site my first question used to be, "do they have proper toilets?" I would refuse to stay on a site if they had holes in the ground. Nowadays everyone has proper toilets.
6. As I have said before, the French Riviera has become much more touristy and crowded. It's still beautiful but you have to share it with lots more people.
