well a few years ago I screwed my neck up by rupturing 2 disks. Since then I have not been on my 4-wheeler because my doc tells my that a simple jolt could possibly paralyze me. Well I'm tired of waiting for the surgery so I got my machine back up and running and I was out on it, very breifly, today for the first time in 3 years. AWESOME. I haven't been in the excruciating pain that I first had when I ruptured them so I'm jumpin back on that thing. Can';t wait for my first all day run. it's like a I got a brand new toy all over again. Anyone else got one?
