MY CUBS CALENDAR

Help me
  1. My family and I are trying to get Cubs tickets again this year.
  2. Are they on sale yet?
  3. I attempted to download a schedule and accidentally synced their schedule with my iPhone calendar.
  4. Now it looks like I'm really busy.
    Or going to every game! God I wish!
  5. How do I undo this?
    Any ideas, listappers?
