Idaho As early as 2016 Dan and Farris Wilks began purchasing large quantities of land in Central Idaho, mainly in Ada, Boise, and
Valley counties. They restricted access to the locals with gates, with anti-vehicle ditches, and with no-trespassing signs appearing soon after their acquisitions. They informed Valley County that they were terminating leases to roads and snowmobile trails, including a main road which was the only access to public lands. According to the
United States Forest Service, some of the brothers' restrictions were illegal. The brothers' restrictions on hunting, snowmobiling, firewood cutting and transit frustrated locals. In 2017 a video emerged of an armed and uniformed DF Development security guard expelling an
outdoorsman from a public road, Forest Road 409 (Clear Creek Road), which runs through Dan and Farris Wilks' land, on grounds of
trespass. According to the Valley County Roads Department superintendent, the DF Development guard was in the wrong, as both the road and a 33-foot easement on either side belong to the county, and as such are public land. As of 2019, Dan and Farris Wilks'
shell company, DF Development, owned approximately 75,000 acres of land across 306 parcels in Valley County. Overall, Dan and Farris Wilks' own about 200,000 acres in Idaho. ==Political activity==
