Hot off the ... television screen. Frontier is back to its famous 24-hour status, according to KOAT-7. Welcome back late-night breakfast burritos, long lines, metal detectors and drunken crazies. To make sure Club Frontier after partiers are safe, a mobile APD will be posted outside. It’s no surprise the weekend hours didn't last. Maybe the short stint showed those trouble markers just what a privilege having the Frontier open at 3:30 a.m. is ... not likely.
