Yeah man that guy does some AWSOME work! Check out the metal work section, there are some VERY talented guys in there too. Even though you can't ride, maybe going to those forums checking them out and talking about them will help. Or maybe they will just make you wish you can ride more I don't know. I don't ride dirt bikes anymore and I go on some motocross or freestyle sites and look at pics of kids hitting 80 foot ramps and wish I can ride again when I can't so I try not to go there too much, just get's me in a bad bummed mood.
If you miss bikes still then ever think about working on them? Like finding old bikes, tinker with them and resell or something? I am just trying to throw idea's at ya you know, seems like you miss it a lot. Would be cool to take up leather work on your spare time and who knows, maybe you got a natural talent and can work your way up to making sweet seats for bikes. Hell it sounds like a job you can do in a wheelchair to me and it would keep ya busy.
Oh and the section on the chopper site about metal work is real good to read up on if your into custom led sleds, etc because there are a lot of helpful people and all that theory like stuff about metal shaping basically is the same for hot rodding. There are some really cool people there though. They made some girl there a bike for her. I think she was making a frame and then some guy showed her how to make a tank over the net and made her one and gave it to her and everyone else threw in parts like bars, fenders, etc and she made a bike. Pretty awsome if you ask me.
