Has anyone else tried the 'Overnighter" method when elk hunting? This is used by some when bulls aren't that active in the day but bugle and rut hard at night. The idea is that you follow the bull all night and call to it, keeping him worked up until dawn, then move in at first light. If things don't work out first thing, and the elk go dormant in the day, you sleep though the afternoon like they do and go hard again just before dark.
Any other experiences or alternate methods for elk that are lazy in the day and active only at night?
