Free: Contests & Raffles.
Walk/bike the roads to find where they crossed the roads, pick the freshest crossing, pick the next road they are likely to cross and go check it out for sign, if sign is fresher then go to the next road they would cross for even fresher sign, when no sign because they haven't crossed yet--then you know which two roads they are in between. Then pick what geographical features and trails in the area to use and move in.
I just jumped a small herd 6 cows and a 4pt bull and they were bedded 50 yds from the road...they bed where they feel safe..most people would of drove right past this spot ....the most success I've had is getting on fresh tracks and just walk them down
You have to hunt where the elk are at. I find that the herds like to make a big loop every ten days +/- a few days. Whatever that lead cow likes and was raised to follow. You can usually find how they make that loop, then it is about finding where they are in that cycle (hence the checking the roads first). There may or may not be a bull (big bull) with them, especially by the time modern and the late seasons come around--one of the problems with checking the herds first.
