Hunting from a wheelchair can be done without much fuss. I have met countless people with disabilities over the years that ended up with them using a wheelchair. Hunting is a common ground where several just stop and no longer hunt. With a few modifications you can be out in the woods pursuing game in no time.

Your injury will be the starting point. If you are a Paraplegic and have full use of your arms and hands your likely already hunting. If you have fingers that do not work there starts the process of finding what will make it work for you. There are devices of all types on the market that may do everything you need but are not always budget friendly.

Using a bent clothes hanger can pull the trigger if your finger cannot move.
With limited use you can always try an EZ-Trigger which reduces the trigger pull to a minimal amount.

Holding a gun or crossbow can be difficult without stomach muscles. Try elevating your chair back some and use your elbow against the arm rest or your knee area.
If that is still too much try and make a brace that goes from one side of your chair to the other that you can use to balance the weapon on. Most chair have spots where things can be mounted on fairly easily with a little work. There are many style available for sale that velcro or attach and detach very easily.

Terrain is my most difficult aspect. Even with a power chair you cannot always access the spot you want. If all else fails call your local Conservation agency and they will attempt to help. Places such as Caney Mountain Conservation Area have people there working for all of us and will be glad to do whatever they can to get you an accessible hunt. Some will even drag a deer out for you and load it. You never know until you ask.

Many states have "Managed Hunts" where disabled hunters can have up to a week in areas to hunt before the regular firearms seasons. Some areas are in animal refuges where the do population control via hunts where x-amount of people draw a tag to go hunting there at a speciffic date. These are typically prized hunting grounds and help is only a call away.

Always attempt to have a buddy with you while hunting or at the very least have a cell phone with reception the entire time.
