In honor of the moody month of February, we visit Ile Saint-Louis, retracing Baudelaire's drug-induced dreams. Our route goes along the central main street, rue de Saint-Louis-en-l'Ile, from West to East.  The first mansion on our route is the Hôtel de Lauzun - where Revolutionary "it girl" Thérésa Cabarrus Tallien lived. For photos, please check out my website. Thanks as always to Bremner Fletcher for technical expertise and general know-how. The Improbable Walks theme music is performed by David Symons, New Orleans accordionist extraordinaire.
