When i picture an "american hunter" i picture a middle aged overweight guy in flannel. Not exactly the most swift or agile type of human out there.
I don't know how many hunters you actually know, but all the ones I know could probably make it out there. Flannel: definitely. Overweight: a little, some of them. Not swift or agile: WTF? The hunters I know don't spend their days sitting in an office chair typing code all day; they carry heavy shit up scaffolding onto roofs, or lug spools of cable into basements and pull it through walls all day, or walk with surveying gear for miles every single day. Physically, they're all in good shape.
If there were a zombie infestation, their biggest liability would be lack of sufficient imagination because, unlike a lot of us Slashdotters, they never liked sci-fi even as kids and stopped playing pretend a long time ago.
