Mackdaddy21,
I haven't, but several of the guys that I work with go after lakers at night in the late fall. They are bunched up on their spawning beds at that time, and they boat some dandies. They release everything that they catch, unless it's over 35 pounds, and the guy who catches it has never caught one that big. Even then they usually let them go.
It got so popular that the Utah DWR closed the Lucerne bay of Flaming Gorge Reservoir to night fishing from October 15th until December 15th. It seems to be just a spawning season kinda thing though. After that most of the guys just fish daylight or dusk.
