Rooster Barn Regional. Logues International Airport. Condit Regional Airport.

An airport boom is underway in southwest Oklahoma. But don't expect to be in long security lines or grab a coffee while you wait for a flight.

These are airstrips registered with the Federal Aviation Administration for private use. Most are turf runways mowed out of a pasture. Some even have a wind sock. But they have no lights or other nighttime warnings.

The rush to register airstrips is part of the fallout from a state law passed last year that put in siting regulations on wind turbines. Senate Bill 808 said the turbines had to be at least 1.5 nautical miles — 9,100 feet — from a school, hospital or airport. The law went into effect in November.
