The doors to discovery will be open and waiting Saturday with Sacramento's 12th annual Museum Day.

Museum Day will open 26 of Sacramento's museums to the community at no charge from 10 a.m. to 4 p.m.

The last guests will be admitted at 4 p.m. and all will close at 5 p.m.

This event is presented by the Sacramento Association of Museums, which promotes a large range of art, history, science and wildlife museums and exhibits.

Museum Day coordinator Delta Pick Mello said last year saw a record 80,000 participants at Museum Day. This year, depending on the weather,

Mello recommended that guests plan to visit only two or three museums on Saturday so they have time for parking and possible crowds.

"Places like there could be just as many visitors. Fairytale Town, Aerospace Museum of California, California State Railroad Museum and the Sacramento Zoo get the biggest crowds, so I encourage people to see exhibits they've never seen such as the Sacramento Historic City Cemetery, Museum of Medical History and the Sojourner Truth Multicultural Arts Museum," she said.

The large list of non-profit museums should give everyone the chance to enjoy a part of history and culture.

"This is a way to provide people, some who may not be able to afford it, access to museums and the right to learn about history," Mello said.

The Sacramento Association of Museums also recommends that visitors take the time to look over the Museum Day details, as well as the different Museums websites, before they attend on Saturday. All that information can be found on their website.
