So, lucky us, because it's a day early, we get to add an extra event. First up is Mambo Combo, a free concert at Watkins Park, 301 Watkins Park Dr. in Upper Marlboro, tonight at 7. If you like some good music, bring a blanket or chairs and head on over.
This weekend is full of fun stuff for the kids. Dinosaur Park, the 41-acre fossil park in Laurel is open for visitors this weekend, with lots of activities (Noon-4 pm Saturday). Also, if you don't mind driving, the Temple Hills Community Center is having a free circus, from Noon - 2 pm (jugglers, acrobats & more). Your older kids can tie-dye t-shirts at the New Carrollton library on Saturday.
Sunday is rife with adventure. For just $5, you can join park rangers on a kayak tour of Berwyn Heights' Lake Artemesia. Want adventure without spending any money? Head over to Greenbelt for a free puppet workshop at 1 pm! Stick around for a gymnastics performance at 3 pm. The details on all these events are on the calendar page.
And of course, you could go to the movies over the weekend. Tomorrow, you'll get my thoughts on whether you should add the Wimpy Kid to your weekend lineup.
