ORIGINAL: Shoulder Strap
All of the above. I would walk a mile in the snow. just to shoot at a crow. I use a tape style caller with a loud speaker. This works very well. my tape has intrmissions where a hoot owl with hoot a few times . We use a hammerin crow call (mouth call ) at the same time. Dont work as well but it will draw in the hawks and if you get the crows excited they will attack the hawk. If you use the tape caller point the speaker horizontal with the ground. If you point it upwards alot of the time they fly in high and are hard to get a good shot. I am a firm believer in camaflauge. If they see you its over.
I'm with you on the camoflauge. I always am completely covered in camo, including my face and hands, and the still seem to see me a lot of times. I've found that you cannot move a muscle until they are within shooting range. I'll have to try the horizontal speaker. Thanks.
