Heck I am 50 and I bet on a 5 acre lot I could put a spear in one, I mean good night the fence is to high for the deer to jump it, so unless the 5 acres is open high fenced pasture I don't feel it would be hard at all. Think about how easy it would be to kill a deer if a guy told you "Okay inside of this fenced in 5 acres is a deer (Garuanteed) go for it"!!!! Unlike real hunting where no one can point to 5 acres and say " I garauntee there is a deer in that 5 acres"! Where is my spear?[8D]
