Yeah, so you can get the chain back on by shifting as though you were going to shift to a larger chainring. That makes the derailleur move back where it should be, taking the chain with it and putting it back on the ring.

I haven't tried it in action yet, but my boyfriend swears that it works. (He did it while I was off the bike and it worked.)

Thanks for the tips gals! I think I am going to go back for other Thursdays - already I'm timing myself when I go by that area for my normal bike ride.
