As if giving blood wasn't gratifying enough, BloodCenter of Wisconsin is making the goodwill gesture even more enticing.

On Friday, July 13, from 12:30-4 p.m., all attempting blood donors at Jansen Fest Hall in the Greenfield Community Center, 7215 W. Cold Spring Rd., will receive one ticket to Cool Waters Family Aquatic Park in West Allis.

The ticket is good for any day and any time in 2012.

BloodCenter of Wisconsin will offer the same incentive from 2:30-7:30 p.m. Thursday, Aug. 2, at the Cool Waters pavilion, 2028 S. 124th Street.

You can schedule an appointment at the Community Center online at www.bcw.edu/coolwater713, or at www.bcw.edu/coolwater802 for the Cool Waters pavilion session. You can also call 877-232-4376, and walk-ins are welcomed.
