AlertDC says a dynamite explosion is scheduled for 2 p.m. at 23rd and Constitution Ave. NW, where a building is set to be demolished. Any idea what building that could possibly be? If memory serves nearly that whole intersection is just baseball diamonds. No streets will need to be closed as a result of the demolition, according to the announcement. If you head down there with a camera, be sure to submit your photos to the DCist Pool.
