Iris is already happy. Young and old, children with parents, everyone is enthusiastic, she says. “Last weekend it was like a festival atmosphere, everyone was busy, there was music and there were snacks.” And also this Tuesday the refreshments are not missing. In addition to the pots of paint, Carin displays several jugs of tea, coffee and biscuits on the table that she brought with her. “Sometimes people come just to chat, that’s nice too.” The plan is to have the tunnel completed within a month. But Iris and Carin also know that it depends on the turnout and the weather.
