I was in the Park on June 18 for the game against the Phillies that was rained out (re-scheduled for September IIRC). I want to go to the re-scheduled game but am unsure of the process. Can I use the original ticket for entry or do I have to go to the box office and get a "new" ticket? If so, is it a regular business hours transaction at the stadium?
You can use your original tickets for the makeup game. More info on rainouts in general (and the 6/18 game specifically) can be found at
