I got a second chance notice last year during the ALCS. I think I got the notice when the Sox were down 2 games to 1. I had a choice between game 6 or 7. Since we were down 2 games to 1, I went for game 7, and got two tickets in the RF grandstand. It was great. Congrats. Enjoy!
Edit: Unfortunately, I couldn't go. I had an early morning meeting in NY, but my son took the trip and went with my daughter who is a student at Northeastern.
