First Mlb game tonight what to expect

As the title says tonight will be my first mlb game and i want to know what to expect. I recently just started getting into mlb last season and wanted to watch it more but being in the middle of buttfuck, Alabama and having a blackout for every team somewhat around me , me and my dad decided to get on the road 7 hours to see the astros play. Hoping to see a lot of homeruns hit and a lot of piss missiles thrown tonight GO ASTROS!!!
