It's a little more expensive than what you'd find at a miniature golf course -- non-members pay $15 for a 15-minute session or $25 for 30 minutes -- but try to hit an 85-mph slider, and you'll get an idea of what real baseball is actually like. With a membership, Breider says he's less expensive than his competition.

Breider and Hunt are also in the process of building a wiffleball field outside the facility, and they expect it to be ready by spring. Dingers is also putting on seminars, the first conducted by former Brewers second baseman Jim Gantner and bullpen coach Ron Nedset. With a lounge upstairs, a pitchers mound for live pitching and catching and a small lunch and snack menu, it's easy to see how Dingers is establishing itself as a must-visit for developing players.

Even the owners and employees find themselves practicing their technique.

"I pretty much sucked," says Bredier. "I was a good defensive player, but now, I'm hitting 80, no problem."

Breider says his customer range from 6 years old to high schoolers to much older softball players, and they have "quite a few members" who are becoming regulars.

Dingers is open seven days a week, and surprisingly, business actually picks up during the winter. In January, players start to get ready for spring.

And some families just come in to play catch indoors. "We try to accommodate all different levels of training," says Hunt.

It's been a fun ride for the couple, though Hunt says customers are still getting used to the idea of buying their practice by the minute, and not by the token.

"People up here just aren't used to that concept yet," she says. "But there's a reason for that. We've had people come in on dates, and we want that, too. But we tell people to keep their mind open, and they'll improve."

Says Hunt, "We didn't want to turn into jungle gyms and basketball courts. This is baseball, and that's been our vision all along."
