I've never minded going in for a game. 75-80 minute drive from Sac, 40 minute train ride, 1 mile walk to the stadium. Going home I'd usually stop at a bar nearby the stadium so the train wasn't super packed. Last train comes around 1230. Game would have to go pretty long to miss that.
I'm ticked because right when the Cubs start coming to Oakland every other year rather than once every 6 years (at most), they're going to leave for Vegas. Sure, would be great if Oakland had a cool stadium and not some run down dump. But it was also nice to be able to buy very affordable lower bowl tickets, which is impossible for Giants-Cubs in SF. In 2016 I went to two games in Oakland. Sat lower bowl, right on third base about 15-20 rows up and paid less per ticket than upper deck behind home plate in SF for Giants-Cubs the same year.
