Aerobic swimming is a popular summer activity for a group of ladies at the Florence Municipal Pool. Edna Robinson, far right, leading the class, has about six women who attend. Trayce Warner of Florence said she has been attending the class for six years, but Williams and Robinson have been attending longer. Morgan is in her second year. If anyone is interested in participating, call Lori Kirkpatrick, pool manager, 620-878-4400. Classes begin at noon Monday, Wednesday and Friday, weather permitting, and last about one hour. ?We do stretching and walking-type exercises for about 30 minutes and then deep water exercises, finishing with more stretching in the shallow end,? Warner said.
