This video is great. I've seen it a couple weeks back on another forum.
I've got a friend here in Billings who was born without arms and very similarly gets by just fine. He rides dirt bikes, drives (drag races), goes trap shooting with us (uses his feet, but I'd bet he could out shoot most) and simply gets by because "not possible" is not in his vocabulary. He's just finished school for engineering and is moving to Portland to be an engineer for a manufacturing facility there based out of Billings. Pretty smart dude, really.
This just goes to show that with the right drive and encouragement anyone can do anything they put their mind to.
