Houston Astros baseball at Enron FieldApprox. Time: 3 hours
Activity Level: Easiest

Check out the beloved Houston Astros baseball team at Enron Field. Aside from all the fun and cheering, especially after the home runs, fans often come for the Enron Field experience. The newly constructed field is something the players-of-old could only dream of. What with the amazing, retractable roof, and real grass field, people can enjoy an open-air ball field with its spectacular city and sky views--unless the Houston heat is unbearable, in which case the roof takes about 12-20 minutes to close and air condition.
