Love section 9, sits down the third baseline near the Cubs dugout. Not behind it though. The first 3 rows are rows a thru c and then the rows are numbered 1 thru 15.
If you want the ultimate fan experience, sit in the bleachers at Wrigley. Infield seats tend to be very affluent, more family oriented. Tickets are very expensive and borderline not worth it. Still love my Cubs.
