Market for nuts, Voiron

Overnight at Voiron near Grenoble. Visibility not good so views are limited, the gentle showers don't help. The sign for a market for nuts intrigued me. There are markets for everything twice a week one of them tomorrow. I'll have a look for lots of nut stalls.
The wrought iron viaduct that crosses the main road is a gem. It's still used to connect with Grenoble and Lyon. I think.
Staying in the Kyriad, a chain of hotels in France. Our third room is OK. The first one flooded the bathroom floor when letting water out of the sink and the second offering stank of smoke.
