Jackson County residents will have free admission to the Kansas City Zoo this Saturday.

Voters in Jackson and Clay counties last fall approved a sales for the zoo, and officials promised some considerations to those counties in return, including reduced admission prices and making school field trips more readily available. Another is a series of free-admission days. Residents need to bring a photo ID with a Jackson or Clay county address.

Zoo hours are 9:30 a.m. to 4 p.m. The zoo is in Swope Park in Kansas City.

Regular admission  is $5 for adults, $4.50 for seniors and $4 for children ages 3 to 11 for Jackson and Clay county residents with a valid ID. It is  $11.50, $10.50 and $8.50 for others.
