Evans Parkway Playground (Silver Spring)

This new playground,  at the intersection of Georgia Avenue and Evans Parkway, has several unique structures, including a ladder bridge, a small maze, and a modern-merry-go-round-like thing whose name I don't know (but the kids certainly like it). There's also a long path for biking/scootering, three small hills, and a round colorful space whose purpose I have yet to determine (edit: I'm told it's an echo center -- see the comments for more detail). Very little shade and no bathrooms, but well-worth a visit -- there's enough there to keep kids busy for a long stay, and a shaded picnic area from which you can easily see the whole playground.

Update: There is also a skateboard track, which seems to appear and disappear on a mysterious schedule. I haven't seen skateboarders all that often, but kids on bikes, scooters, and their own two legs also seem to enjoy it.
