I think you may be interested in a new trick used by some sleazy guides. When the birds are not on the land they have leased they go where the birds are. When the land is private and unposted they take their clients on this land. These guys dont ask permission they just hunt and leave. The trick is these guys go into the field at about 10;30 PM park a truck out there and leave the lights on. Anyone who may be interested in hunting the field thinks that someone is already setting up. The battery runs down but they just jump it. They show up when they want to and have the field to themselves. The guy that does this is a pig! Also anyone that hunts with this guy has pretty low standards.
