Thought of this watching the Yankees-Orioles and I see it's already a thread. My choices:
1. Camden Yards. Not a bad seat in the place, classic look, love the warehouse and great concessions.
2. PNC Park. Surprisingly underrated.
3. Original Busch- good views and great atmosphere
4. Kaufman Stadium- scenic and great views everywhere.
5. Ballpark at Arlington- GREAT setup, classic style.
6. Nationals Park
7. GABP
8. Miller Park (did get to stand in the batters box and sit in the dugouts there though)
9. New Busch
10. Citizens Bank
11. Turner
12. Riverfront Stadium
13. Altanta Fulton County Stadium
14. Vet
15. Pro Player Stadium (Marlins original)
16. RFK (Nationals original)
Got to walk through Wrigley and US Cellular but haven't seen games there. Went by Yankee Stadium and Shea.
Kauffman was one of the nicer parks before the renovation. Now it's even nicer. It is often bragged about and modeled after.
