When they turned onto their new street, staked in the grassy front lawns of nearly every home were U.S. flags, waving in the breeze. The program also has spread to other rotary clubs in the Dallas area and outside the state. "People want to show their colors by flying the flag," said Chuck Koehler, a charter member and chairman of the flag program. For $50 each year, residents pay to have the flags raised and taken down for six holidays, beginning with Memorial Day and ending with Veterans Day. Most of the funds are dedicated to building an all-abilities playground in McKinney — an addition to Bonnie Wenk Park that includes equipment accessible to kids with developmental delays, special sensory requirements and other physical challenges. Sunrise has teamed with the Rotary Club of McKinney to raise funds for the project. "There's a lot of pride in doing the flag program," said Paul Powell, member of the McKinney club and co-chairman of its flag program. If their neighbor gets a flag, they've got to have one, too, Koehler said outside a storage unit where the club keeps about 2,500 flags.
