I want to know the answer to the following question:
What year was the first full season with night baseball at Wrigley Field?
All the background I'm provided with is that "After splitting the first two games at home, the Cubs headed to the Bay Area, where despite holding a lead at some point in each of the next three games, bullpen meltdowns and managerial blunders ultimately led to three straight losses.". Is that enough to answer the question?
Answer: no
