A GLIMPSE OF THE HIDDEN PECAN AT 509 LOUISIANA ST., NOW THAT THE BUILDING IS OUT OF THE WAY While much of the 1906 structure that formerly stood at 509 Louisiana St. was still on site as of early afternoon yesterday, the pieces had mostly been rearranged. A couple of excavators can be seen picking them over in this shot sent in by a reader. The once-secret pecan tree is also hanging out in the open as it waits for the axe  — look for the branches peeking out around the corner of the Calpine Center parking garage entrance, on the left edge of the shot.
