Have some time on Sunday? Have an extra $10-$13 on you? This sounds like an excellent opportunity to get to know the neighborhood's history and culture (and get a little exercise in).
Thanks to Kristen Goode, Brooklyn's connection at About.com , for sending this my way...I'd have had no idea otherwise!
