As I said before, hunting a predator is different than hunting prey. Prey animals you can track/stalk/wait for on their normal trails and habitat and even then it's not "easy" but it's at least reasonable. Predators are doing the same thing you are doing when you hunt a prey animal, they are out tracking sources of food whether it is an animal or a berry patch. Which means they can be pretty much anywhere, there isn't a lot of pattern involved unless there is a steady food source that they always come back to which isn't usually the case with most predators.
Predators also have very keen senses, not that a deer is stupid but it's definitely easier to sneak up on a deer than it is a bear or coyote. I'm not saying it doesn't happen and sometimes the bear doesn't think you're sneaking up on it, sometimes it wants to see what you are, see if maybe you're prey.
So without bait and dogs, your option is to literally wander the woods looking for a black animal that sleeps during most daylight hours and has extremely keen senses to know when you're coming. There would still be some success, but at that point it's more just luck than anything else, it would be very rare in those circumstances for an animal to be taken. It would also greatly increase the risk to the hunters who are out wandering the area trying to come across a 150->500+lb animal that would be content to eat them.
