WARREN — Two exhibitions open today at Trumbull Art Gallery.

The Warren gallery is the final stop for “Where Sidewalks End,” which opened in August at Youngstown’s Soap Gallery and also was displayed at the Random Acts of Artists Gallery & Art Emporium in Sharon, Pa.

Two photographers were selected from each participating county — Rachel E. Hathhorn and Mikenna McClurg from Trumbull, Michael McAllister and Joseph Napier from Mahoning and Tim Cimperman and Gil Thurman from Mercer County in Pennsylvania — to document infrastructure in their communities. William Mullane is the overall curator for the project with a separate curator working on each county (James Shuttic, Trumbull; Stephen Poullas, Mahoning; Terry Polonsky, Mercer).

Sarah Lowery, director of Healthy Community Partnership-Mahoning Valley, said in August the idea behind the exhibition was, “To start a conversation about what our built environment could look like and how to get better connected to the places we need to go as well as each other.”

The public also was invited to submit digital images of the infrastructure where they live, and those pictures will be incorporated into the show as well.

In conjunction with “Where Sidewalks End,” Jacob Van Sickle, executive director of Bike Cleveland, will give a presentation from 5 to 7 p.m. Monday at TAG. He will talk about the work being done by Bike Cleveland, what they have learned and the resources available to help cyclists.

Also on display “Is Less More?: The History of Minimal Living in the United States.” Created by the Trumbull County Historical Society with support from the Community Foundation of the Mahoning Valley, the exhibit explores how people have tried living with less over the years, from Henry Thoreau’s retreat to the woods to the current advice of organizing consultant Marie Kondo, star of the Netflix series “Tidying Up with Marie Kondo.”

Both exhibitions will be on display through Dec. 27 at Trumbull Art Gallery, 158 N. Park Ave., Warren, where an opening reception is scheduled 6 to 8 p.m. Saturday. Admission is free. Gallery hours are noon to 4 p.m. Tuesday through Saturday. For more information, call 330-395-4876.
