Thanks for all the tips and concearns guys.
I talked to him this weekend and he said he tried to shoot his bow setting in a soft chair and he can't. He said he got up with his crutches and after he was standing he was able to shoot. I told him not to rush it but he's planning on still going to Illinois in a week and a half. He paid an outfitter $3,000 dollars for a combo hunt and he says he's going.
Thanks again guys!
