Accessible from either N. Culpepper St. or N. Brandywine St., I tend to use this odd little park as a short cut to get to Glebe Road from my neck of the woods. At some point in time, a number of trees were cut down here, but that seems years ago as many of the stumps are sprouting new saplings. You're looking for a nano (BYOP). And though it's off the beaten bath, this park is popular with dog walkers, so some stealth may be required.
Congrats to seadog129 for FTF!
