Yankee: you can "upgrade" there too. During my last NYC visit (mainly for the US tennis open) I did visit also a Yankee-game (they game had a rain delay of about 2 hours 59 minutes - and at the end - after ankees even lost). During the rain delay I did stand at the entrance of a distinctive Yankee club-restaurant talking swiss-german to a friend. Somebody past by, asked in high-german if we want to enter the club-restaurant and gave us two vouchers to get in, saying he did his studies long long ago in Switzerland and was happy to do us a favor (I don't think it was Mr. d'Amato ...). So there are upgrades to at baseball-stadiums.
