It’s time to sign up for the Sister Bay Community Rummage Sale, coming up on May 21. Sister Bay-area homeowners who’d like to clean out their garages and attics, and make a little money, should plan to sell this day. The registration form is available now at sisterbaywi.gov or at the Sister Bay Advancement Association office at 10668 N. Bay Shore Drive. That registration form, along with $10, must be dropped off at the SBAA Office by May 2 in order to be included in all the advertising. The SBAA office is also where sellers will pick up their signs and maps before the sale.
