The math

Regular adult admission at SF Zoo is $32, so timing the visit to the free window keeps $64 in a couple's pocket and up to $128 for a family of four — each month it comes around. That's what San Francisco residents with a government-issued ID showing an SF address — one free admission per qualifying ID leave on the table every time they pay walk-up prices.
