Does NY have a disabled sportsmens association? Pa has one that is very effective. We've had a crossbow permit available for the disabled for quite a few years now.
Might want to contact these folks, maybe they can help put you on to local disabled sportsmen and get your cause organized.

It might even warrant a visit to your local staterepresentatives office. It's an election year and sponsoring ANY legislation for the disabled looks good on a political record. Idon't trustmost politicians but this would be a win win if you could get one to take up your cause.
It'sjust plain common sense for the pysically challenged and older hunters. You can point to Pennsylvania if you get many naysayers. The crossbow has been here now for several years with certain restrictions and the predictions once heard that it would ruin bowhunting have failed to come true. It hasn't even had much impact in the special regulation areas where the able bodied are allowed to use it.
