My oldest reads to dogs at the local library. There was a photographer there the first time we were there:

It's kind of scary. She's only in first grade, but she's reading at what's at least a third-grade level. We thought at first she might only be skimming, but we have her do book reports now and she remembers characters, settings, plots, and subplots.
I think she might be getting a wee bit bored with the picture books they're reading at school...
