Unless he does something stupid during the rut KB got it right.This guy will be leaving his bed late in the PM and returning early AM.Slim to no chance you'll catch this guy while out feeding.You'll have to figure out a way to get as close as possible to his bedding area without him catching on to have any chance at all.Be sure to keep AM/PM air thermals in mind!!!I hope you can work it out.
Good luck!
