Jessie and Reagan Moore each grabbed one end of a saw and took turns pushing it back and forth.
The 9-year-old Philipsburg twins were timed to see how fast they could cut through a log that was about 18 inches in diameter.
When the saw spit through the wood, the girls nearly dropped.
“Wow. My arms are sore,” Reagan said with a sigh. “I’m kind of out of breath.”
Never miss a local story.
They were participating in the log crosscut activity at Black Moshannon State Park’s 29th annual Summer Festival, which celebrated Lumber Day activities Saturday.
At another activity, Kyler and Riley Freedman each took one end of a 300-pound log.
The brothers from Snow Shoe each dug a cant hook into the ends of the log and attempted to roll it from one checkpoint to the next in the fastest time.
Volunteer Tim Gleason said professionals could do it in about 30 seconds while amateurs take up to eight minutes.
The Freedman brothers took 4 minutes and 51 seconds.
“The hardest part was figuring out how to hook the log,” Kyler Freedman, 22, said. “Once we got it, it was pretty easy.”
The festival attracts around 3,000 to 5,000 people annually, depending on the weather. Only three years were rained out, said longtime volunteer Betsy Schnarrs, of Allport.
Schnarrs, 76, is an original member of Friends of Black Moshannon, which sponsors the festival, and has volunteered since it started.
“It’s grown so much over the years,” Schnarrs said. “We started with just a few activities and vendors, and now take up a big part of the park.”
The festival includes activities for children and adults, live entertainment, and 30 arts and crafts vendors.
This year, the event is helping to raise money for the Friends of Black Moshannon to build a jungle gym near the beach area.
So far, it has raised about $6,000, Schnarrs said Saturday afternoon. The goal is to raise $25,000.
“This is what we do,” she said. “We want to make the park a place where people want to come and come back to.”
The festival will continue 10 a.m. to 10 p.m. Sunday, and will feature an appearance by Smokey Bear for his 70th birthday.
Other events include boat building and canoe and kayak races.
