Les Arcs/Draguignan area is pleasing in the small ways that some people seek in Provence. Restaurants and small wineries dot the rolling countryside. Farmer's markets move from town to town during the week. St-Tropez is an hour's drive away. The spectacular gorges at Verdon (not the Verdun up north) can make an easy day-trip.
As a long-time regional centre, Draguignan has its share of well-aged buildings and historical connections. One notable site, from the Second World War, is the Rhone American Cemetery and Memorial which commemorates the second invasion, after Normandy. US troops landed on the southern beaches, including such now-notable crescents as St-Tropez, linked up with the French irregulars and headed north to meet the main forces at Lyon. Overshadowed by the northern actions, this part of the war deserves a respectful look.

The French army maintains an artillery school just east of the town. It allows the public to visit its museum covering many wars, although I couldn't find a link showing the hours. The tourist office in the middle of town (2 Ave. Carnot) can probably help. There are also aging military pieces parked around the compound although the training manoeuvres are located well to the northeast.

The region is called Dracenie and has this website which includes a schedule of public markets http://w3.tourisme-dracenie.com/modules/news5/index.php?storytopic=16 (in French).

I wouldn't be too worried about what is in the markets.

We had an apartment in Aix about 4 years ago, that was directly across from the large marketplace in town. The one shown on Rick Steeves and elsewhere.

My wife saw an apple that she wanted to buy. After looking at the sticker on the apple, it read 'Chile'.

Try this for the mistral.
