You might think that Frisco is just a tree-barren concrete jungle of McMansions housing white-bread kids whose idea of diversity is having the option of eating ketchup on their cheeseburgers instead of mayo. And you might be right. But within the northern exurb of 100,000-plus citizens are some fairly attractive destinations, not the least of which is Fieldhouse USA, which is meant to provide an amazing sports venue for these same kids. The 144,000-square-foot, state-of-the-art indoor sports facility features 12 basketball courts (reconfigurable for volleyball or whatever), a turf-laden field for indoor soccer, flag football, kickball and lacrosse. Its "there's a sport for everyone" philosophy includes older coots too, who can join a fitness boot camp or an adult soccer or basketball league if their backs and knees will let them.
