In my experience, calls don't work where I hunt whatsoever.(MN) They haven't worked in years and years of trying different calls and rattling. I think there needs to be a good doe to buck ratio for them to be effective. We just don't have it where i hunt. Way too many does around for the bucks to be concerned about fighting for them. Now i think a good scent can be effective though. I prefer code blue, i'd swear on that stuff.
