We went to the Canal du Midi, about 1990. One of the great trips of our life. Went from the western side, where it crosses over the Garonne River at a height of >100', to Béziers, where it goes down 5 locks. We walked into Béziers and helped them celebrate Midsummer Night. Went through Toulouse, where we were attacked by a swan. The Airbus is assembled there and we toured a 12th century cathedral. Went to Carcassone, an old walled city started by the Romans, now restored.
Rented a small boat one way, the locks were mostly do-it-yourself. If there was a lock tender, he sold you wine. A great tour of Province: small towns, farming country. Nearly missed the train to Paris, it was moving when I jumped on. Judy had a birthday on the boat, moored in the middle of an industrial district. Ate some very good meals. A great trip. Wow, just remembering it.
