Children don't play outside here in the summer, and they go to school armed. Nearly everyone is enlisted in the battle against Public Enemy No. 1 - mosquitoes.
Located where the Missouri and Yellowstone rivers meet, Williston is a kind of mosquito mecca, where breeding abounds.``They're bad,' says Kellee Cox, 23. ``I went into my back yard and got swarmed with them,' she says, revealing dozens of red bites on her arms.
Some have proposed building a bubble over the town or setting up huge fans to blow them away.
But a new idea emerged from a heated city meeting last summer: The local high school, a woodworking club and the Army Corps of Engineers are making mini-houses along the river, each designed to attract bats and sparrows - natural mosquito predators.
