Don't think anyone is referring to disabled in any way. Only referring to the illegal and unethical actions taken by the OP....I'd bet your gramps knows the regs and abides by them when he is out hunting, especially with the limitations he has.
There is nothing wrong with road hunting when done legally. There are some hunters who look down on road hunting and seem to think they are better than anyone who road hunts, but as long as it's done legally and ethically then I see nothing wrong with it. My advice would be that you need to be out of the vehicle before you load your gun and please pay attention for private property. Always think safety first and please follow the hunting laws. Good luck on future hunts, I hope to hear about your experiences.
