RWK, I don't know of your exact physical reasons for not being able to use a bow. But have you tried contacting New York Bowhunters? They have a special Physically Challenged commitee, that is more then willing to help out physically unabled persons shoot a bow. They have done wonders for many, many people. They often display the special equipment at sportsman shows.
I've been involved in the crossbow issue for the past several yrs. Personally I don't agree with the many reason crossbow manufacturers have proclaimed to get their foot in the door of NYS to fill their pockets of $. Cross Bow manufacturers want to invade our archery seasons to sell their products. They don't care about ethics of our archery sport.
Personally I don't have a problem with someone whose absolutely unable to draw a bow to continue hunting during archery season if they have exhausted all other efforts. To use a cross bow.
But I do have a problem with capable hunters using a weapon thats obviously a advantage to our present archery equipment in the woods. A crossbow is always cocked, and loaded. Shoulder held, fired by a stock trigger mechanism. Its capable of greater poundages, and speeds. Its distance accuracy has a longer range. It can be scoped. Simply put its NOT A BOW.
