RE: crossbows in new york
Steve,
I have interest in Xbows for handicapped in NY after I saw that is not currently allowed today, or at least only to the most severely handicapped. I also have interest in all other states with backwards game laws and regulations.
For your other question, in NJ someone with a disability can get a doctors note stating that they are unable to draw or hold a bow due to their disability. They can then apply to the state for a permit to use a crossbow during regular archery season. We've had this system in place for as long as I can remember and there isn't any push that I have seen to legalize crossbows for everyone during regular bow season.
