RE: If it's easy to shoot a deer, does it lose it's challenge?
I must not be as fortunate as others here! We see our share of deer but it has yet to become "guaranteed"! I think I'd quit hunting them if it did.
Anyway, to keep things interesting, I'm always changing my tactics and methods. I switched to a bow. I started trying more spot and stalking, you get the idea.
Heck, there are lots of ways to make it difficult. Try hunting them with a spear!
