Well Marc I see nothing has changed in Cow bay! We used to get the same only prolly 20+ skybusters all over the area. Usually just us with our deke's and calls watching guys shoot at birds up to 200 yds up with no gear or means to retrieve even. So we gave it up after a few yrs and found quieter places.
The other thing about Cow bay then was we found after a few weeks the birds got real gunshy and very few would come into call/decoy.
