i have a 15 game pack for Comerica, this is typical
Ticket (upper deck behind home plate) - $22
Parking - $10 (4 of us go, non-drivers split it)
Street Peanuts - $1.50
Beer (x3 or 4) - $6.50-$8.50 depenidng on if i want a 16oz can or 20oz draft = $34 worst case
Food - usually between $0-$10 depening on if i eat before/after
so...a typical worst case game for me is about $72.50 (tickets were pre-paid so about $50 a game x 15 games = $1087.50/year

). My wife says since we are having a baby that that number will be severely reduced (i'll probably grab 2 or 3 single game tickets but in better sections)
cant wait till Saturday to watch Verlander smoke the White Sux
