We just got back from our second day in a row of grocery shopping at Carrefour (one of the largest grocery-everything stores in Europe. We slipped into our backpacks and headed up the hill...30 + minutes up, 30 back with a lot of walking around another grocery store (Lidle) and a large and beautiful general mall. We left about 10:30 and got back with full packs at 3:30pm.
