Check the Kp forecast before you pick a night, not a spot
Fairbanks' aurora season runs late August through April, but the clearest skies pair with February and March's equinox boost in geomagnetic activity. Check the Kp index and short-term forecast the same evening you head out rather than committing to a spot days in advance; a strong forecast turns even Creamer's Field into a good night, and a quiet one won't save the darkest corridor.
