crows are easy to get close to...al you need are 2 things:
Crow call
Camo
ok, i forgot about patience but it helps too. crows are smart but dumb. they know when trouble is coming, but they will answer to and go to crow calls like its a homing beacon. i took my call out back one day after crows left, started calling, and what would you know within 15 seconds had crows circling above looking for whatever was calling them!
ps: nice pics! im goin to my grandpas camp this weekend with a few rolls of film. i hope i can get some good b+w pics of his place, if so ill post them here!
