I love Montana first week of October. Hate her last week of September. I'll probably never hunt the general tag again in September...too many dudes, elk won't bugle during legal shooting hours, etc.
I've kind of gotten away from it the last few years, but almost every morning my plan is to get to a glassing knob in the dark and sit and listen, maybe rip a bugle in the dark. If I hear a bugle on the way in I can change plans, if I hear a bugle off the knob I can change plans, and if no bugles I can sit and glass country for miles around. Doing this yields
something more often than it doesn't...either I hear a bugle or I glass up elk and can take action. As
@mad_angler mentioned, you can also use your glassing knob to look for the next spot...maybe a knob you can look into country you can't look into from where you are.
