From funding one of the city's first public parks, to providing college scholarships, to helping develop such institutions as the Child Study Center, the Tarrant Literacy Coalition and Fort Worth Citizens Organized Against Crime (the precursor of today's SafeCity Commission), Rotarians have used their wisdom, wit and wealth to help create a vibrant and progressive community.The roots were planted when 12 Fort Worth businessmen determined that their rough-and-tumble city needed some civilizing influences.

The next day, they will gather on the banks of the Trinity River for a special groundbreaking.Rotary Park, the club's centennial gift to Fort Worth, will be a trailhead that connects with an existing trail.

The monument from the original Rotary Park, built in 1916, will be displayed in the wheel's center.The Rotary Club of Fort Worth has helped our community survive wars, floods, droughts and depressions. One of the wonderful and enduring characteristics of our members is their sense of camaraderie and humor. We may be part of a worldwide civic organization that puts service above self, but there are few clubs that advance fellowship and goodwill more enthusiastically than this one.Bob Bolen if a former Fort Worth mayor and Rotary member since 1982.
