Best Astros game day experience for a visitor.

Hey Astros fans I'm visiting Houston from Atlanta and want to get an authentic game day experience of the die hard fans. Where do I go before the game? I have seats in right field and looking to explore the park before game and take pictures are there any specific monuments or anything I need to make sure I find in the stadium? Is there a gathering spot after the game? I plan on getting inside as soon as doors open to walk around . Thanks for any tips
