It’s a mix of cold and warm views of Chicago and Evanston skylines in this edition of Grid Shots.

The Evanston skyline is seen in the background from this view over the Chicago Transit Authority’s Howard yard for Red, Yellow, and Purple Line trains. Photo by Alton Park.

Another view of the CTA Green Line along Lake Street, but this time from Ashland Avenue. Photo by Eric Pancer.

People swim and sunbathe on the concrete beach along the Lakefront Trail, a view of good times that are just around the corner. Photo by Michelle Stenzel.

Next week’s Grid Shots theme is “Art on the street” (April 8). See the full schedule. Submit your photos for consideration to our Flickr group; tag it with “art”.
