In a lot of ways Lincoln Heights, Ohio sounds just like any other suburb.

If you walk around town, you'll hear kids playing outside the local elementary school. You'll hear the

highway that takes commuters down to Cincinnati. At the woods on the edge of town, the

bird song is delightful.

Lincoln Heights is small, less than one square mile with about 3,100 people.

It's a quiet residential place that seems far from the bustle of the city, even though

it's just 13 miles north of Cincinnati. It's the kind of place where everyone knows everyone.

If you live there, it's hard to get anywhere in town

without someone stopping you to say hi. There are well-kept single-family homes and

low-lying apartment complexes. People gather in their grassy backyards for cookouts and in parking lots for pickup basketball games.

The town feels calm and peaceful, at least until the gunfire starts. Most weekdays it begins in the morning and lasts through the afternoon.

Sometimes it goes past sundown and occasionally into the weekends.

Once the shooting begins, it comes in rapid-fire waves throughout the day. People say it makes it hard to focus or relax and those who work the

night shift say they can't sleep. Residents worry about what the gunfire is doing

to their hearing and their stress levels. They're especially concerned about

their kids who are listening to gunshots all day long while they're trying to play or study.

The noise of gunfire isn't from street violence. It all comes from an open-air gun range

that's owned by the Cincinnati Police Department.

This thing is huge, the size of about 22 football fields.

It sits just outside of Lincoln Heights, right along the town's northern border. And the cops use it a lot.
