The reason for crossBOWS being allowed in archery season is because they have a short enough range that MOST hunters KNOW what they are shooting at. Everyone during the season can wear camo safely. NOT because they are harder/easier than a bow or gun. they just fire a similar projectile.
Personally, I like the rules here in WI. handicapped, or over 65 can use a crossbow.
But I have nothing agains't xBows...just don't sound like as much fun to ME.
BTW...not quite a spear, bit they are trying to pass the atladl (spelling?) basically a spear thrown with a long wooden ladle!!!
