Free admission days are rare at Zoo Boise, so when one pops up in our calendar it's always worth shouting (or roaring?) about. Even better, this particular free day revolves around that upcoming hearts-a-flutter holiday, Valentine's Day, so it's the perfect time to cart the kids downtown and remind them how much they love animals. The event, which runs from 10 a.m.-5 p.m., includes plenty of themed activities like face painting, photo opportunities and unique "animal enrichments" to celebrate all things Cupid. Kids can even make Valentine's Day cards for their favorite animals—and we promise that zoo staff won't let them eat the messages.
