Things to do in downtown Columbus: Catch a ball game at Golden Park (left), go to a concert or event at the Civic Center (white dome), ride bikes or walk on the Riverwalk (right), kayak, ski, or fish on the Chattahoochee River, or, a favorite of mine: Catch the Columbus and Chattahoochee's afternoon switcher as they negotiate the riverfront trackage to work an industry along the river!
