TWO HARBORS - Sidewalks in Two Harbors will be undergoing a transformation this weekend, chalk–style.Chalk–O–Lot, as it’s known happens along Waterfront Drive between Second and Third Avenue. Artists buy a sidewalk square that includes a free clinic, instructions and materials to get artistic. "There are a lot of people that came to the clinic today that had no idea how well they could draw and using the grid format they did really, really well," said Michelle Ronning, of the city’s Arts and Beautification Committee. There's a free chalk event for kids on Saturday. The day will wrap up with the movie Chocolat at dusk.
