The weekends of May are packed with activity; there's Cinco de Mayo, Mother's Day, Memorial Day, and that one weekend without a holiday. There are parades, festivals, shows, and people eating bugs. With so much going on, it's easy to miss something. To help you keep track, here's a list of the biggest, most once-a-year-ish events happening this month. We'll keep adding to our Event Calendar daily, and it's a good idea to make sure our weekly recommendations arrive in your inbox, but we figured you'd appreciate some advance notice on these May favorites.

We just got word that Annenberg PetSpace's new summer camp is already full for the season—that didn't take long! But even if you missed it, there are still a whole bunch of wonderful reasons to bring kids to explore this unique, critter-focused community space, many of which are free. The center has educational programs and play opportunities that include story hours, classes, scavenger hunts, birthday parties, and more—all created to strengthen the bond between pets and people. If you thought Annenberg PetSpace was just an adoption center, get ready to take a closer look.

Southern California is blessed with some of the world's most famous theme parks; families travel from all over to experience Disneyland and the original Universal Studios Hollywood (including the Wizarding World of Harry Potter)—but just 90 miles to the south, in the San Diego suburb of Carlsbad, is a park that has at least as much to offer as the mouse and the wizard. There is a whole lot more to Legoland California than bricks, and truth be told I prefer a day there to any other major theme park.
