So glad she's okay.
I watched someone totally wipe out on a bike (I was driving the following car in Race Across America many years ago) and it was not easy. You see it happening and there is nothing you can do.
Luckily she woke up this morning and didn't mention the crash until I asked how her body was feeling - and wanted to get back on the bike tonight. So, hopefully no long-term harm for her, at least :)
