If people are working with this weather and our transit system i beat there are tonnes of people lining up to get in. When i went to a 4pm playoff game in 2016 it took close to 45 minutes to wait in line, get through security and seated. I missed the 1st 2 innings... i would wait until the 3rd inning to judge the size of the crowd.
I can't imagine showing up any less than 1 hour before start time for a major ball game.
