The pushka challenge is to put something into a pushka every day, e.g. 36 cents a day.  When your pushka is full, empty it into a ziplock bag marked with your name, and drop it into the locked mailbox at 3310 W. Strathmore Avenue. If it is difficult for you to drop it off, please contact Shlomo and Ahuva Goldberger at 410-358-4456 to arrange a pickup
