529 will give Cubs fans a great vantage point and is a great route to go if you just want to get out of the house to see the Cubs in person without spending a whole lot of money. Sight lines are good from the second level but when you read '500s' on your tickets, you think those seats are terrible.
Nothing special about 529 but no complaints either. If you enjoy the new high tech stadiums with the walk up music and silly games on the jumbo tron, you go drive 8 miles south for that stuff. Wrigley is strictly old time baseball.
