Usually here they cover a lot of territory. They may be around for a few days or until two or three out of the sounder get shot and you won't see them again for weeks. They say a sounder can have a territory anywhere from a hundred square miles to four hundred square miles and covering twenty miles in a single night isn't unusual.
I've found that they get cravings. Protein is a big one, certain plants and trace elements is another. Here they seem to crave earthworms. And at other times certain plants. I planted a plot of Watercress in a seep and they periodically hit the Watercress hard.
I also put out a plot of Lovage. many years old now. (

Feeders and baiting is forbidden (regulated) here, more than a pound of Corn cannot be used. So we have gotten sneaky. Fish guts, offal and blood meal will draw them in, especially if they get hungry for protean.
A giant steaming pile of horse manure, straw, compost (kitchen waste) and Chicken bones works as well as a corn feeder.
