Marabunta- i'm glad to hear that you're getting regular progress on the left side, and am sorry to hear about the lack of progress on your right. My daughter is about the same age as yours- thankfully she lets me change her on the floor.
I used to ride also... My college graduation present to myself was a Trek 6700 mountain bike.... I rode my new bike 2 to 3 times a week for just under 2 years before I couldn't ride anymore. Right now, its hanging on the wall in our garage- I see it any time I go out the garage door.

Oh- right after I saw Rocky, Invincible was on- grrreat! Another get-pumped-up sports movie. based on the true story of Vince Papale who went from bartender to the Philadelphia Eagles in the late 70's.
