It sounds like Aly is fine (she tweeted about being excited for their next show later this week) and hopefully McKayla heals up quickly and completely. Poor thing.
BTW-My mom and I saw the gymnastics tour they did after the 2008 Olympics and it was really fun (it still had a few cheesy moments but overall it was pretty good). Not sure if we're going to see this one yet though. It doesn't come here until November so we have time to figure that out.
