I took a bow hunting class at Conservation camp... It's crazy how deer can multiply. In a few years one couple can multiply so that theres like 20 deer. It's nuts! And if we've already killed off their natural predators, it's sort of up to us to keep them under control. The ecosystem is a delicate thing.
I wouldn't shoot a deer (or anything else) unless it was for meat. For me, archery is an awesome skill to have, and I really appriciate it, and bows don't frighten me and freak me out as much as guns. I see it sort of like sportfishing- if you're going to eat it, awesome, great catch! If you're not, then shame on you for wasting a life.
So great shoot!
