Voss v. Albany County Comm'rs
In Voss v. Albany County Comm'rs, 74 P.3d 714 (Wyo. 2003), the Court concluded a personal thirty year right-of-way grant/temporary use permit over BLM land was not "legally enforceable access" to the public road in question--a county road. Voss, P13, 74 P.3d at 719.

Furthermore, the permit was personal and did not "pass automatically upon conveyance of the property." Id.
