Charlie, Texas doesn't issue crossbow permits for the disabled. All they have to have is a doctor's letter. A problem with your back, even a shoulder, doesn't qualify. It has to be an upper limb disability. Here's the regulation:

"ONLY a person with an upper-limb disability* may use a crossbow to hunt deer and turkey during the Archery Only Open Season, provided the person, while hunting, has in their immediate possession a physician?s statement certifying the extent of the disability.

An *upper-limb disability is a permanent loss of the use of fingers, hand, or arm in a manner that renders the person incapable of using lawful archery equipment."

Probably a lot of guys ask their doctors for letters and the doctors never read the regulation.
