Thursdays in April they have a program called tunes and Blooms. Admission is free after 530pm. There are more details on their webpage.
No. I haven't heard or seen anything about that. They had half price admission January-March but that's over. Active military, vets and first responders get in free on Memorial day, the 4th and Veterans Day. If you have a membership to a partner zoo, you can get free reciprocal admission anytime.
