SENNETT -- The Sunday afternoon heat and leftover exhaustion from a one-mile fun run were not enough to discourage dozens of children from enjoying the jumpy house and inflatable slide set up for the 12th annual Majorpalooza.

As soon as their parents parked the car in the Auburn Correctional Facility's recreation center parking lot, the children jumped out and ran toward the inflatable structures, screaming in excitement as they tore off their socks and shoes mid-stride.

"It takes my kids a little while to warm up but once they get going they wont stop," said Auburn resident Heidi Church as she watched her children, Rieley, 11, and Zac, 8, climb up a flight of stairs before plunging off the top of the 30-foot high slide.

"Last year they were beat by the time we were done, and they will probably be exhausted this year too," she said. "We will definitely come back next year."

Chris Major, the event's organizer, said Majorpalooza originally began as a backyard barbecue and eventually grew into a cheap party for families while raising money for local charities.

This year's event, which includes a 5 kilometer race and one-mile children's fun run, will benefit the Matthew House, Hospice of the Finger Lakes and Relay for Life.

While Major admitted he could easily double the amount of money the event raises, he said it was important to balance cheap family-oriented activities with raising money.

"We could make more money if we doubled the entrance fee, but I want to keep the prices down," Major said. "I think it's important to provide free food and entertainment while families spent time together. That's what this is about."

As 6-year-old Alayna Foos munched on a hamburger and potato chips, she could only give a thumbs up to the fun she was having with her 8-year-old sister, Maya, and her father, Terrance Foos.

"It's really for a great cause and my daughters love it," said Foos. "They ran in the fun run and they did great and they came here and played in the jumpy house."

While the afternoon was aimed at providing fun for her children, Church said she planned to return to Majorpalooza later in the evening to listen to some of live music with her friends.

"There is stuff for everybody to do; this is just a great event for the families," Church said. "I will come back tonight. Motley Crouton and Johnny Bender are playing later tonight so I want to listen to them after I take the children home."
