Help restore my daddys faith in humanity

Most everyone who knows us,  know that my daddy has stage 4 lung cancer. We've came to the point where there's nothing more they can do to fight it. It's in Gods hands now. He seen a commercial of a scooter \walker that would really help him out. The problem is that it's 750$ and we simply don't have it to spare. I was speaking to him about setting up a gofundme to get it,  and his response was,  "nobody cares these days". So help me in proving him wrong. Let's get this Walker for him! If you can't help monentarily then please share this like crazy and of course prayers are always appreciated. I want to prove to him that the world isn't always a dark place. We were told that there isn't much time left with him,  so let's prove that people DO care. Thank you for reading.
