We live in Mt. Washington, a couple blocks from Pimlico, so I'm looking forward to spending Saturday selling Handiwipes and lake trout sandwiches (not necessarily in that order) to the Kegasus-heeding revelers from the infield staggering past our house, and Sunday cleaning their vomit off the kids bikes.
If that doesn't sound appealing to you, maybe you want to head Saturday to the Faerie Rings and Eco Things Festival at the Carrie Murphy Nature Center, a multicultural celebration and fundraiser with all kinds of crafts, jewelry, food and faerie dust, or the Ahrens-Fox Day at the Fire Museum of Maryland, a celebration and parade of these unique and rare machines from various eras. There's also Baltimore Humane Society's Paws on Parade, which not only features parading paws, but an "ask the vet" booth, demonstrations by rescue dogs, a bake sale, and more.
On Sunday, you can prepare your kids for a lifetime of grueling physical competition - or just a nice day in the park - at the Make-a-Wish Baltimore Kids Triathalon at the Padonia Park Club or get creative at Family Fun Day at the Avenue in White Marsh.
Of course, there are always the perrenially great-for-kids activities, including the Walters, which, besides the great, often kid-friendly exhibits, has a fantastic play area on the lower level with lots of dress up stuff, puppets, puzzles, and an art room where there are facilitators to help you and are kids make great projects and bonus: FREE; Also, the Marlyland Science Center ($3 off admission before noon on Saturdays, plus the weekly egg-drop contest), Port Discovery Children's Museum, The Zoo, two Storyville locations (we LOVE Storyville), The American Visionary Art Museum (also with kid-friendly exhibits, and the treehouse/sculpture out back), the various nature centers and conservancies (Oregon Ridge, Irvine, Howard County), and—of course!— the Aquarium.
