"Are they actually doing anything yet with the Trinity River project?" So asks my husband, who continually drives over Dallas' giant open sewer and reports no visible progress. He does spend a lot of time in Fort Worth, however, and has walked many miles along the Trinity Trails. These 30 miles of paved, landscaped trails can be accessed at numerous points—including Northside Drive off of Interstate 35W. The trails wind through Heritage Park, Trinity Park and Overton Park. For some reason, Fort Worth's Trinity never stinks. You can walk, bike or Rollerblade and not worry about getting grazed by a stray bullet or bombarded by exploding acetylene tanks. When it comes to river amenities, Cowtown rules.
