It should be another hopping weekend at The Flea at One Hanson this weekend. In addition to the regular hundred or so vendors of antiques, vintage clothing and other memorabilia, there are a couple of new food vendors setting up shop downstairs in the old bank vault: Jam maker Anarchy in a Jar and East Village pretzel purveyor Sigmund. Yum. The Brooklyn Flea will be taking place every Saturday and Sunday through the end of March from 10 am to 5 pm at One Hanson Place. You can take any number of subways to the Atlantic Terminal or the C train to Lafayette.
