I have hunted them for years with a selfbow. Although the selfbow adds a challange it has never been the bows fault that I didnt get my bird. I have always run and gun, no blind and a single decoy. I have had lots of birds in my range, and missed more than I want to admit to. Others have spotted movement but I like that challenge over blind hunting. My guess would be out of 5 birds I bring into my range, I will get drawn or a shot off at 1. I like that extra challange. I have located a creek that greens up early and I may try Centaur's method of lying in ambush, sign tells me birds feed along the creek at some point during the day, because the birds have not been gobbling durning the season up in high country I hunt.
Centaur stop by sometime on your snowbird travels and I will set you up with a selfbow that will not come apart on you.
