What IS "trackstanding"?  Heard about it loads but still don't know exactly what it means...

EDIT - just seen that Pashley adult tricycle - I *have* to get one of those!  We had a three wheeler at the blind school and it kicked arse - especially with 3 of us in the basket (we were all <12 y/o when we had access to that bohemoth!).

Riding down the steps in it was one hell of a rush!
