Retired cowboy Tom Bunn and his ranch dog Wink are a familiar site around town these days as Tom walks for exercise. In the spirit of Earth Day April 22, Tom picks up garbage around town on his walks, and Wink carries his blanket, doggie bags and treats in his own little saddle pack. Here the pair stopped by to check out how the Earth Day mural painting project at Delainey’s Mall on Oliver Street was coming along.
