for the past couple of months a buddy and i have been going to this 3d shoot at a local archery shop in canterbury nh. the place is cool. there is 15 separate lanes in the woods where you have to look for the 3d target, then you pick a pin to stand at which are at certain yards or less and judge the distance. i have to say i am getting much better at judging distances but buying new arrows are not very cheap at all. im gonna have to invest in a rangefinder because i dont want to get caught in the woods not quite sure how far away my dinner is. lol!
