CITGO Petroleum Corporation is taking 200 local students out to the ballgame for CITGO Day at Wrigley Field as part of the CITGO Lemont Refinery’s 90th anniversary celebration. These students will be CITGO special guests for the 7:05pm Cubs game against the Pittsburgh Pirates on Wednesday, August 31, with each child receiving a commemorative t-shirt and Cubs dollars for snacks. All Cubs fans attending the game have the chance to join in on the fun: the first 10,000 fans will receive Cubs player decals presented by CITGO.
