When Catie Sykes met 3-year-old Silas Edenfield, he was pale, bald and his stomach distended.

But then, and afterward when the toddler was hospitalized, Sykes didn't hear him complain - not after multiple surgeries, not when nurses drew his blood and not when he faced death.

"As soon as you talked to him, he just lit up the room," said Sykes, an Armstrong sophomore. "He was so excited to go to heaven, and get his new body and be with Jesus."

Edenfield died of a rare liver cancer this past summer at age 4. But Sykes and her Tri Sigma sorority sisters still raise money for the group that helped Edenfield and other children battling cancer.

To help the Tri Sigma sisters help children, slip on your dancing shoes.

They will host a 15-hour Dance-A-Thon from Feb. 21-22 at Armstrong's Aquatics and Recreation Center.

Most of the money goes to CURE Childhood Cancer, an Atlanta nonprofit dedicated to finding cures for childhood cancer.

"They do tons of research for kids, particularly in Georgia," Sykes said.

The rest of the money funds a benefit dinner this spring for another local family struggling with childhood cancer.

Dancing starts at 5 p.m. Feb. 21, before a candlelight vigil where Edenfield's mother will speak about Silas' journey.

The vigil opens the "more serious side" of the event, according to Sigma sister Rebecca Hefner. It's when people see why Sigma sisters are "so passionate" about funding CURE.

The night will be fun, too, according to Hefner.

Dinner - $5 for a barbecue sandwich, baked beans and coleslaw - sponsored by Sticky Fingers, follows the vigil at 7 p.m.

Another family helped by CURE speaks at 8 p.m., then it's back to dancing until the sun rises.

They'll play music of various genres such as swing tunes and sounds from the '50s through the '80s.

"It'll all be clean," Sykes said of the music. "Family-friendly."

Activities will also be set up for children, and people are welcome to bring sleeping bags "and dance when you feel like it," Sykes said.

But to be eligible for the prizes, someone from each team has to be dancing the whole night, according to Sykes.

Dancing categories include: Individuals, couples and teams made of three to 12 people.

"Decide if you want to dance all day and night on your own, with your partner or organize a team," Sykes said.

Dancers will learn different moves, including one dance they'll learn in parts throughout the night before putting it all together at the end of the event.

"Everybody who participates will know it at the end of the Dance-A-Thon," Hefner said.

Sigma sisters will also give prizes, including restaurant gift cards, as the hours wane on.

Costumes are encouraged, and prizes for dress will be awarded. Army Rangers will reportedly show up in ballerina dresses, according to Sykes.

The last dance begins at 7:30 a.m. before a grand-prize giveaway. Sisters then announce the amount of money raised.

"We are here to have fun and to raise money, but we have to remember what it's for," Hefner said.

Edenfield "just really grabbed a hold of our hearts so much," she said.

"He had just turned 4. It was really hard," Sykes said of his death. "I think people forget that kids get cancer, too."

People can also donate online through Sigma Sigma Sigma. All donations are tax-deductible and go both to CURE Childhood Cancer and help support another child with cancer.
