The Texas Rangers play in arguably the most under-rated ballpark in the majors, Ameriquest Field. Sure, because it's an open air stadium, you'll cook if you're sitting in the left-field bleachers (especially during day games). But view of the field looks good even in the upper deck. Plus, Chuck Morgan does an excellent job on the in-game entertainment aspect.
Unfortunately, Tom Hicks hasn't committed enough money to improve the on-field product. But if it's wholesome family fun that you're looking for on the Dallas/Fort Worth sports scene, a Rangers game will fit the bill.
