This one was given away at the Cubs Convention in January. It's got a cover that's a little more exciting than the one on the previous schedule.
Most year there would still be two or three more schedules to collect. The Cubs should be putting out another one soon that would replace the convention schedule. Those I usually get by calling or emailing the Cubs directly.
The there usuals would be from WGN TV and radio. There will be no WGN radio schedule since the games have moved to WBBM. Will they put out a schedule? WGN TV has a limited number of games this year, only 45 games, and none on the cable version, WGN America. I doubt they'll put out a schedule with so few games on their station.
