Under myczech site, click on 'language', then 'links'(bottom left), then 'language', then 'Brown university online', then go to texts. They've got stories, with audio, and you can read as they read, which to me seems very fast by the way, especially 'Šlépěje', but it's an interesting story about mysterious tracks in the snow.
Just had a look myself. Looks a very useful and interesting site. Thanks for the link - MyChechRepublic as well as Scrimshaw
