The Square Society will have its only membership drive of the year tonight.
The event will start at 6 at the O. Winston Link Museum.
The Square Society will help Center in the Square celebrate its 30th anniversary this year.
The Center will reopen in May after a long renovation.
The Square Society has donated more than $270,000 to Center in the Square over its 17 years, said the non-profit's president, Jenny Roberts.
Membership fees will also be reduced for this one night only, according to the charity organization Facebook page.
