I started calling elk when I was thirteen ; I'll be fifty-six in April...I've called elk in almost every year since I started...AND as far as I can tell; elk are about as predictable as the wind...from what I've experienced most of it depends on the mood their in...sometimes it works and sometimes it doesn't...I think I call less every year mainly because I call in a lot more hunters than elk...it does get discouraging..I've been in several contests(even won a couple)with some mighty big name callers..not trying to toot my horn just trying to say I have some background on the subject.I have seen huge mature bulls throw caution to the wind and charge right in when their hot; on the other hand I've had more than one gather up the harem and haul..point being : they do what they do. The "experts" generally get to hunt in areas the rest of us can't; LOTS OF ELK WITH LOTS OF ENCOUNTERS. If you watch enough "huntin" shows you start to believe em....just saying
