In one week I'll be resuming the walking tours with the Van Alen Institute that we had organized together last fall. Three different tours will be taking place between April 7 and May 26, all starting at Van Alen Books: One heads north to Bryant Park, one heads west to the High Line, and one heads south to Union Square; all are about two miles and take 2-3 hours. The initial 2012 tour next weekend meanders up Broadway, Madison, and Park Avenue to 42nd Street and Bryant Park.
Head to Van Alen's event page or Facebook for more information. Tours are $15 General / $10 for Van Alen members. Send an email to firstname.lastname@example.org to reserve spot.
