I speak only from my home state of Idaho hunting experience. I mostly only bait for them in the Spring, but do see them quite frequently in the fall when elk hunting.
For a fall hunting season with no baiting the best chance is going to be hounds. Most hound hunters LOVE to run bears and are very willing to let you tag along to shoot one after it is treed. The hound hunters I've known will go run bears every chance they get, even if they know they themselves aren't ready to shoot one, and then will just walk away from a treed bear if that's what they have to do. They've told me that they hate to have to walk away from a bear too many times and not "reward" the dogs with a bear tumbling out of the tree, so they will take along most anyone with a valid tag that can keep up and appears to be a safe minded person gun wise. Start spreading the word around, you may be surprised with the offers. Most would probably only ask you to kick in fuel money at most. At least that's how it is here in Idaho.
The second option is to hunt clear cuts (or good sized openings) very early morning and late evening. I see them quite often when glassing out clear cuts when archery elk hunting in September. Especially if there are berry patches. Get the wind right and stalk in on them. You can often get pretty close as long as you don't move when they are looking, only move when they aren't looking your way and are occupied eating. You can be standing in the wide open when they look and as long as you aren't moving you'll usually be fine. This option only works well if you can observe a clear cut from a good vantage point with the wind in your favor. Their nose is king...if they smell you they are gone.
The third option is trying to call one in. Like Widude said, it isn't a very high percentage option. Fawn distress would be my choice of call too. Does may charge in on you too to "protect" the fawn.
Here's a pic of a pretty little blond phase bear that was hitting my bait last year. I had other bears quite a bit bigger hitting the bait too, but this one is my #1 target this year. He'll be around 6 or 7 years old this year. I wouldn't mind giving him (I'm fairly certain it's a boar) another couple of years, but don't think I'll be able to resist if he shows while I'm sitting on the bait.
