Landscapes of the imagination: The latest in a series

For a long time - since first reading Borges? or was it Bioy? - we've had a sweet spot for stories about imaginary and semi-imaginary places.  We track the odd website covering such spots, and of course have run a story or few that, while neither Borgesian nor Bioyish, lets the reader revel in being in a place that isn't, and the writer run afield, as it were, in making it at once fantastic, and utterly not - some writers giving us more of the former, natch, while others, rather less.  So imagine our delight when K.M. Weaver's new short-short, "Laguna de Vuelo," came across the transom.  And yours, we hope, on reading it, right here.
