Even as good as most GPS units are now, they are not designed to be closer than about 10-15 feet due to the Feds not wanting them to be exact for defense purposes.
This hasn't been true for a long, long time. The selective variability on GPS signals was eliminated a long time ago.
In the past, the accuracy was way worse than 10-15 feet when the signals were still being "scrambled"...
As to corner crossing, I would do it in a heartbeat and never even worry about it. The only time I've heard of it being a problem in Wyoming is when someone takes a short cut rather than cross at the actual corner.
The case in Albany County was ruled on by Robert Castor.
GREEN RIVER - Douglas hunter Bill Kearney always suspected it wasn't illegal to corner jump over private land while hunting. Now he has a state opinion backing up his contention.
The Douglas sportsmen was acquitted of trespass charges in April after he used a Global Positioning System (GPS) device to step from one parcel of public land to another while hunting in Albany County in September 2003. The practice is known as corner jumping or corner crossing.
The case prompted the Wyoming Game and Fish Department to seek a State Attorney General opinion reviewing the agency's long-standing assumption that corner jumping is illegal.
The AG opinion released by the department said corner jumping from one parcel of public land to another in order to hunt on the other public parcel does not violate Game and Fish regulations.
The opinion said corner jumping does not violate agency rules because, to be convicted, the rules require a person must hunt or intend to hunt on private property without permission. Corner jumping, however, may be a criminal trespass under state law, the opinion said.
"I'm just delighted with (the opinion) and think it's great … it was certainly worth spending the money and challenging this in court," Kearney said.
"A real positive aspect of the opinion is with the increasing pressure from hunters and sportsmen and rockhounds and whoever … it's a good thing that could result in public access to large tracts of public lands," he said.
