Tigers Stadium: My cousins all grew up in southwest Detroit, you can see it from their back yard
Comerica Park: (great spot to get drunk at, the view is great)
Palace of Auburn Hills (Magic @ Pistons Shaq's rookie year; once again on Christmas 2005)
Joe Louis Arena (multiple Red Wings games)
Pontiac Silverdome (Lions old spot, got to watch Barry Sanders have a 100+ yard game in a loss to the Saints)
Ford Field (Lions current spot- but I went to see K-Deezy, Too $hort and 3-6 Mafia at a car show on the football field).
Magic tickets were sold out when I was in Orlando, they were in the Playoffs. So just those 6 places.
