RE: LINING UP ON A PUSH
Yup, you have to coordinate the push or you will fail. You need to plan with the shooters, the drivers and the blockers. We most often have successful pushes when we spend 5-10 minutes planning who posts where and in what direction we'll be pushing from, etc. The lay of the land factors in as well. Plus, we use radios so the drivers can report on how many deer we got running and where the blockers need to block. Also, this lets the posters know if there are racks in the herd and when to expect the deer to come busting thru.
In year's past, we've done drives that it took us an hour or more to get the herd from one area into where our posters were located. That was one long ass drive up hills, in ravines, etc. We were productive because we planned the drive and communicated.
