all depends on terrain and cover. my best hunt i made it within 50 or 60yds of the birds. i had a 10yd walk from the edge of the field into the woods..i had little cover but was able to slip in somehow. tree called a bit. did a fly down..they landed on my lap and it was over. talk about text book lol. but it depends on terrain and cover..if theres no cover or a way to get close you might not beable to get close..i like to push the envelope and get as close as possble sometimes. funny thing is ive gotten busted on that same ridge many times lol. i havent been able to do it again since. another thing i like to do is find somewhere the bird cant see me..but i can set up the decoy so that the bird can see it. same area, diffrent roost site ill get within 100yds of the bird..crawl(literally) out onto a gasline he can see from the roost and setup the decoy and crawl back..then when hes getting ready to fly down ill hit the call. think that was last year..worked great...but every morning i was there a couple of idiots would come walking into my setup..
