(This should definitely be filed under Information That Would Have Been More Useful Two Days Ago, but it's not like it's not still hot and won't get hot again.)
I figure that most parents of small children in the Near Southeast/Capitol Hill/Southwest metroplex are already aware of this, but it's still worth mentioning that DC Parks and Rec's Lincoln Capper Children's Pool
at 555 L St., SE, is open again this summer, offering splashing opportunities from 10 am to 6 pm Wednesday through Friday (with a half-hour break from 2:30-3 pm), and on Saturdays and Sundays from noon to 6 pm.
The fountains and wading pool at the Yards Park
are now probably a bigger draw, but this additional offering brought to you by your tax dollars shouldn't be neglected, especially if it's too hot to walk down to 3rd and Water or if it's during the times each week when the fountains are off
