Cantrell Gallery will open an exhibition of photographs by Paul Caldwell on Friday, June 27, and host a reception for Caldwell from 6-8 p.m. The show is called “The Places in Arkansas That Keep Calling Me Back” and features shots of seven of the Little Rock photographer’s favorite places in the state. (Hemmed-in Hollow, above, is surely one of everyone’s favorites.) Caldwell has been making photographs of Arkansas landscapes for 30 years; call him the Arkansas Traveler.
