A guy needs vast amounts of contacts for land access depending what areas the crows are using.
My partner calls it "the tour" when we go out on the road and are gone for 7 to 10 days, sometimes two weeks if the shooting holds out where your not spinning your wheel's. The past two seasons the weather conditions killed us but this season we are making up for it. We are due to head out sometime next week and the areas we return to can change dramatically in 3 to 4 weeks time in regard to there patterns. I usually arrive a day before my partner to scout out the area so we have good intel on the crows movements and Dick picks up the tab for a very nice dinner the evening he arrives. The last two seasons I never had to buy ammo but this season it's going down at a rapid rate so far, note I said so far.
Here is an example of how conditions can either help or hurt you.
Dick and I had a hell of a morning shoot two weeks ago where we shot 314 crows in 2 1/2 hours and were pretty much done. We needed it breezy ( 10 to 15 mph ) for the afternoon hunt and the weather man got the report all wrong and it was calm ( 5 mph or less ) so we just staked out the spot but did not setup as we already knew the birds would be flying way out of gun shot range. Sure enough we were in the right spot alright but with the wrong weather conditions for a bang up shoot. Those crows flew for two straight hours through that area. Had we got the right conditions a 500 bird day could have been easily attained.
That spot gets better later when the feed is harder to come by out in the fields. They don't have to go to a place like that right now because there is feed everywhere.
