Steve writes about the Matthew Henson Trail:
I walked from the Layhill Rd starting point to the Georgia Ave/Hewitt Ave intersection. All of the construction is complete along this section and I even spotted a cyclist trying it out this morning. The boardwalk is bare and doesn't seem to have any reasonable traction for inclement weather, but that doesn't mean they won't get around to adding something (let's hope).
And notes that nothing is open west of Georgia Avenue.
