RE: please tell me just one negative to crossbows
I see what you're saying, data.
I have to agree that it is interesting to make distinctions about how a given device is held or operated.
I live and hunt in Ohio. Although crossbows get no negative press, an awful lot of people consider a compound bow kill a bigger challenge than a crossbow kill.
With that in mind, in Ohio the crossbow has had no detrimental effect on the herd or whitetail hunting in general that I know of.
