I've had the same bow for 10 years, and can pick it up and start shooting 4 inch groups at 30 yards. Two weeks of practice and I'm softball sized at 40 yards. I've got 13/20 and 20/20 vision.

In NY and New England, unless I'm setup on a field edge, I will not shoot past 30 yards. Even with good form, precision, and great vision, I still can't see pencil thin branches. And I've hit too many of those at 35-40 yards to deal with that frustration any further
