If I were ten people instead of one, here's what I'd try to pack in this weekend. Want more? The full calendar is here. (What'd I miss? Post your picks in comments!)
1. Head north to Concrete to observe hundreds of wintering eagles on the Skagit and enjoy the many other events of the annual Skagit Eagle Festival. (Sat. and Sun.)
2. Celebrate Groundfrog Day in Snohomish: entertainment, games and a local bullfrog that will give a "frogcast." (Sat.)
3. Welcome the Year of the Dragon with a free Lunar New Year festival at Hing Hay Park in Seattle's International District. (Sat.)
4. Learn the nuts and bolts of how a city works at the free Seattle City Hall open house -- entertainment and a farmers market, too. (Sat.)
5. Planes + music = free family fun, right? Find out on Saturday by attending the launch of a unique initiative at SeaTac Airport and rocking with Recess Monkey. (Sat.)
6. Explore aquatic life forms by night with the help of a guided naturalist at Tacoma Nature Center's Pier Peer event (registration required). (Sat.)
7. Attend a musical -- The Frog Prince, Little Women, Singin' in the Rain and Hairspray all open this weekend! Or book tickets for next weekend.
8. Celebrate Tacoma's Native American heritage, arts and culture at Tacoma Art Museum. (Sun.)
10. Let Metro Parks Tacoma chauffeur you to Mt. Rainier for a day of snow play on Sunday, or -- if it's too late this time -- book one of the other three next Snow Family Fun Trips.
