["yote"]

I've been hunting labs for 30 yrs and have come to a few conclusions. If at all possible, I only hunt my dogs INTO the wind.
On strip cover, {railroad tracks, drainage ditches or frence-rows}
I hunt them into or cross wind. That gives them the opportunity
to smell the most ground. Hunting with the wind makes them
"snorkel sniff " or do a constant back-track thing. When hunting
strip-cover, work the hound on the down-wind side of the cover
so that it can smell everything in the cover. Hope this helps.

P.S. Stay away from hunting "with the wind" if at all possible.
All you end up doing is "herding" birds and in the end they will
usually end up escaping out the end unless you have posters.
