OK, I an a novice, only been once, but headed back in 2011. Here's my 2 cents:
Spend the money for the right gear to do backcountry:
1) You need a sleeping bag that'll keep you warm even if the temps are unseasonably cold (we nearly froze in front country in 2009). There is a good chance of snow at elk elevations in Sept., and even if it doesn't dump enough to chase you down, it'll still be damn cold at night.
2) You also need to have the right gear to get you pack weight down to something you can manage. Some UL backpackers can go a week on 25 lbs, but maybe 40 is a more reasonable goal for elk hunting. Still mine was over 40 when I left home. A good but light bag, shelter and pack will help you drop weight, but a pack that'll haul out elk quarters seems to be heavier than the same volume internal built for rec backpackers. Personally, I'm still looking for the right bag, but the one I carried was not it.
Read everything you can on the subject, I got 4 new books for Xmas on elk hunting! I'm near the end of Backcountry Bowhunting (C. Hanes) now. Good book, but he is not my kinda bowhunter (wheels and horn porn . . .). Lot's of good info on how he does it and hunting hard. Also, it is clear from his book that they take long shots. I do not expect to ever feel Ok about 50 yard shots, but every extra foot that you can shoot buys you more opportunities!
Don't give up and always be ready! Oh, and never underestimate elk. They can show up in some unexpected spots. I nearly swalloed my toothbrush one a.m. when they were right across the meadow (about half a mile).
Don't think of elk hunting like whitetails, think more like turkeys with much larger brains. We were even using a decoy, but didn't have any luck with it. Like Elknut says in his book, turkey tactics can pay off if two hunters can work together, but you've gotta be at least 40 yards apart imo; some more experienced elk hunters say up to 100 yards. Twice we were able to call a bull back to us but he locked up just outta sight. If the shooter had been outta sight of the caller, he should have been closer to the bull and maybe w/in shooting distance.
Be prepared, but definitely go. Oh, and live right so the gods will smile on you, especially the god of wind . . .
BTW, the tag in CO costs more than $500 and though you can hunt from a road for less, I figure a backcountry hunt will cost you about another grand in gear, unless you are already into winter camping in snow country! But look at it this way, I've got a buddy that figures it is gonna cost $1000 to start any new hobby: kayaking, mtn biking, fly fishing, you name it!
Just my 2 cents.
