My grandpa was killed by a drunk driver so I love that the Phillies and Budweiser offer a designated driver program where people who agree to serve as their friends' DD are rewarded with a voucher for a free soda. When you sign up for the program during a ballgame, you show your ID and get a paper wristband identifying you as a designated driver. I have been the designated driver for my friends on more than one occasion so I enjoyed getting something in return. The staff also like to advertise this as well. Good job Philadelphia!
Having only been there once and as a guest of the opposing team media, I really did not get any insider tips. I did learn that tailgating is big for most games, and if we go back, I plan to take full advantage of that.
