LINDON Many Utah families have trampolines in their back yards.
In fact, they're about as plentiful in Utah as pools are in other, more balmy climates.
Meanwhile, inflatable slides and other types of trampolines are popular at fast-food restaurants, county fairs and city celebrations.
Now Carl Alger and his wife have come up with a new business that combines all that. Jump On It has 10,000 square feet of indoor, gymnasium-size trampolines and blow-ups. The business, located in an industrial area just off I-15, caters to kids, families, birthday parties, church groups, school field trips and corporate events.
The Algers got the idea about eight years ago from a trampoline entertainment center in another state.
"We had a blast," Alger said. "Since then I've always wanted to do this."
His dream came to fruition on Aug. 3 when the couple opened the doors to the new business.
So far as he knows, it's the only business like it in Utah with so many trampolines 71 of them. A 2,500-square-foot area is reserved for kids under 4 feet tall, while a larger 7,500-square-foot area is designated for older kids and adults.
Some of the trampolines hang off the walls at a 45-degree angle so jumpers can get enough momentum to bounce from trampoline to trampoline.
Watching dozens of jumpers having fun looks as chaotic as a mountainside full of skiers, but for those in the middle of it, it's not quite so crazy, he said.
"This is not just for kids. It's for anyone from age 1 to 80," he said.
Alger calls it a low-impact sport because it isn't as hard on the joints as running or jumping on a hard surface.
On the side of the mammoth warehouse the couple built three party rooms for birthdays or other events.
"People can come, hold a party and leave the mess," he said.
Kids up to 3 years old are admitted free, while youngsters ages 4-8 pay $4 an hour. Those 9 and up pay $8 an hour ($5 for the second hour). Jump On It can accommodate as many as 120 jumpers and 250 partygoers throughout the entire building.
Fridays, Saturdays and Mondays are the busiest days."Jumpers usually stay just an hour because they get so tired out," Alger said.
