I don't think you can argue about #1 on that list. It was so impactful on the Cubs march to the WS win.
The Mariners game was awesome because of how the pitchers played such unconventional roles. It was a Sunday night game, and we were on our way to vacation up on Lake Superior. We had to stop to see a friend of Mrs. Lucas in the Twin Cities, so we got a room about an hour north of there. The game went late, and the kids and wife were not happy about the game being on in the hotel room.
One off of the list that I love was from 2015, mainly because I was there. Monday night game against the Rockies where the Cubs had crapped away a late lead. Fowler led off the 9th with a double, and Bryant mashed one. I have the picture of the scrum at home plate as a screen saver.
10ish years ago I was at a game in the bleachers, also against the Rockies, that was fantastic. The game started late because of rain, and after the front passed through the wind kicked up. It was so windy you couldn't keep a hat on your head. We had a large group, and couldn't get seats together, so we scrambled up onto the concrete blocks below the scoreboard. I'm not sure if that is even allowed anymore. Awesome boob watching spot in addition to a great place to watch a game. The Rockies were up 8-1 after 2 innings. The Cubs pecked away with homers from Henry Blanco, Micah Freaking Huffpauir, and two from Jim Edmonds. Sheer pandemonium in the bleachers.
