Lets see, I am 26 and from Oklahoma I won't scream "BOOMER SOONER" I think Billy Sims did enough of that. Anyways I just fixed up a go kart for my son for Christmas. I didn't build it from ground up but I did put a lot of time into it and it sparked a new hobby. Now I have a mini bike in the works as well as an old gas powered golf cart frame and diff that I am hoping to make into an off road buggy. That's pretty much it. Here is the before and after of my first kart, nothing special but I think my 6 y/o should like it.
