County Line Rule

Definition – County Line

(As Defined by: Sonny – W5VDW – from

A county-line is that legally defined boundary separating two geographic and/or administrative regions. The best evidence of the location of a county-line is the marker permanently placed beside a highway. The marker will be assumed to be correctly placed for county-hunting purposes, except for those at wet lines.

Other devices may be found on secondary roadways, such as, a cattle gates/cattle guards, or a monument placed in the fence line. Frequently, too, changes in the composition of the roadway surface are an indication of county boundaries. For county hunting purposes, when no other means of identifying a county line is available, these markers may be used.

With the degradation of GPS having been turned off on 1 May 2000, GPS may be useful as an aid in locating county-lines. While the accuracy of GPS is now a nominal +/- 20 meters, it may be relied upon only when other markers and evidence are not apparent.

A county-line may be run with credit being given for both counties. A part of the vehicle must be in each of the counties. Thus, a county-line may not be credited if the mobile is in motion.

A county-line may be "wet"; that is, a watercourse (river, lake, water reservoir, creek, brook, or stream) may cover the legally described boundary. A wet line may be run for county-hunting credit as long as the County Line can be located as described above and can be run SAFELY.

Three and four county lines may not be run simultaneously for county-hunting credit.


Mobile operators are reminded that the integrity of all parties concerned is at stake. If one is engaged in a specific goal, for example, USA-CA or working all county-lines, and contact is made knowingly to be in error both parties may suffer accusations of dishonesty.
