I expect crossbows will be legal soon enough. Heck in Missouri you can kill deer in just about any fashion you want. Shoot 'em with any centerfire rifle, handgun, shotgun slug, stick 'em with an arrow shot from a bow, chuck a spear at 'em, knife 'em, beat 'em in the head with a rock, strangle 'em with yer bare hands, run over 'em with the truck as long as you don't run down a farmers fence... don't much matter as long as you slap a tag on 'em.
Pardon the Ozark humor, some of that is even true. On a serious note, I hear that there is a big push for the crossbow and it is very likely to be authorized soon.
